National Vendors 157 MDB Board Snack Machine – Refurbished Commercial Snack Vending Machine

The National Vendors 157 MDB Board Snack Machine is a full-size commercial snack vending machine built for operators who want capacity, flexibility, and modern payment compatibility. This refurbished National snack machine combines a proven vending cabinet with an MDB electronic control system, DEX capability, dual snack spirals, and room for a wide mix of popular products.

The machine features an attractive Ultra Black appearance. It has six shelves and a 5-wide snack configuration. Depending on how the trays are set up, the machine provides approximately 30 to 40 selections. This gives vending operators plenty of room to create a varied snack menu.

Use it for chips, candy, cookies, crackers, pastries, granola bars, nuts, and many other packaged snacks. Product sizes and spiral configurations will determine what fits each selection.

Another major advantage is the MDB PC board. MDB technology makes the National Vendors 157 better suited to modern vending operations. The machine is also listed as credit card capable. A compatible credit card reader can be added separately.

Important: A credit card reader is not included with the machine. Credit card capable means the machine has electronics that can support compatible cashless payment equipment. A reader, service plan, installation, and related equipment may involve additional costs.

A Commercial Snack Machine for Serious Vending Locations

Small countertop vending machines can work in certain situations. However, a full-size snack machine offers much more room for inventory and product variety.

The National Vendors 157 is designed as a commercial vending machine. Its larger cabinet gives an operator space for a broad product mix. Instead of being limited to only a handful of snacks, you can create a menu that appeals to many different customers.

That can be useful in offices, warehouses, employee break rooms, apartment communities, service businesses, waiting areas, and many other indoor locations.

A larger machine can also reduce the need for constant restocking compared with very small vending equipment. Actual service frequency will depend on sales volume, product capacity, and the location.

Six Shelves for a Flexible Product Mix

This National snack vending machine comes with six shelves. The shelf layout gives operators flexibility when deciding what to sell.

A vending location rarely has only one type of customer. Some people want chips. Others want candy. Some prefer crackers or cookies. Others may look for nuts, granola bars, or similar packaged products.

Having six shelves makes it easier to divide the machine into useful product groups.

Possible Snack Categories

  • Potato chips
  • Tortilla chips
  • Pretzels
  • Popcorn
  • Crackers
  • Cookies
  • Candy bars
  • Chocolate products
  • Granola bars
  • Protein bars
  • Fruit snacks
  • Packaged pastries
  • Nuts
  • Trail mix
  • Other packaged vending products

The exact products that fit will depend on package size, shelf spacing, and spiral configuration. Operators should test products before filling a complete selection.

Approximately 30 to 40 Snack Selections

Product variety can be a major part of a successful snack vending program. The National Vendors 157 offers approximately 30 to 40 selections, depending on its configuration.

That selection range gives operators room to test different products. You can stock proven sellers while also leaving space for new items.

For example, an operator could dedicate some selections to traditional snacks and others to newer choices. This makes it easier to adjust the product mix as customer preferences become clear.

Not every location sells the same products at the same rate. A warehouse may have different demand than an office. A gym may require a different product mix than an apartment building.

A vending machine with many selections gives you more room to adapt.

5-Wide Snack Machine Design

The National Vendors 157 uses a 5-wide snack machine configuration. This provides a useful balance between machine width, capacity, and product variety.

The layout is designed for commercial vending use. Operators can arrange the shelves to create an organized product presentation.

A clear layout also helps customers make faster buying decisions. They can view the available products through the front of the machine, enter the selection, pay, and receive their snack.

For operators, the wide cabinet provides space to build a balanced snack menu without needing several small machines in the same location.

Dual Spiral Snack Delivery

The National Vendors 157 is listed with dual spiral snack selections.

Spirals are one of the most common product delivery methods used in snack vending machines. Products sit between the turns of the spiral. When a purchase is made, the vending motor turns the spiral and moves the selected item forward.

At the end of the vend cycle, the product drops into the delivery area.

Dual spirals can provide additional support for certain snack packages. This is especially useful when a package benefits from more even movement during the vend cycle.

Why Spiral Setup Matters

Correct spiral setup is important in any snack vending machine. Products vary in width, depth, thickness, and packaging material.

A spiral that works well for one product may not be ideal for another.

Operators should test each product before fully loading a column. This helps confirm that the package moves correctly and drops into the delivery area.

Simple product testing can reduce service calls and improve customer satisfaction.

MDB PC Board

One of the most important features of this National Vendors 157 is its MDB PC board.

MDB stands for Multi-Drop Bus. It is a communication system widely used in commercial vending equipment.

MDB allows compatible vending components to communicate through a standardized interface. Depending on the equipment and installation, MDB can support devices such as coin mechanisms, bill validators, and cashless payment hardware.

For a vending operator, MDB capability can make an older commercial cabinet more useful in a modern vending environment.

It is especially important for operators who plan to investigate cashless payment options.

Why MDB Capability Is Important

Payment habits have changed. Many customers still use cash, but many also expect electronic payment options.

An MDB-equipped vending machine gives the operator more flexibility when considering compatible payment upgrades.

Instead of being limited to a basic cash-only control system, an MDB machine can support a wider range of compatible vending peripherals.

Compatibility still needs to be confirmed before purchasing or installing any accessory. A specific card reader, validator, coin mechanism, harness, or other component should be checked for compatibility with the machine and its existing electronics.

Credit Card Capable Snack Vending Machine

The National Vendors 157 offered here is listed as credit card capable.

This can be a major advantage for vending operators who want to add cashless payment equipment.

However, it is important to understand exactly what credit card capable means.

The machine does not include a credit card reader.

Credit card capable means the machine's electronics are designed to support compatible card reader equipment. The reader and any required installation, activation, wireless service, merchant processing, or other services are separate.

Always confirm compatibility before purchasing a reader.

Possible Benefits of Adding Cashless Payment

When a compatible cashless system is installed, customers may be able to use payment methods supported by that specific reader and service.

The exact payment options depend on the card reader, processor, service plan, and equipment selected.

For many vending locations, offering both cash and cashless payment gives customers more ways to make a purchase.

DEX Protocol Capability

The National Vendors 157 is also listed with DEX protocol.

DEX is associated with vending data exchange. It can be useful in vending operations that use compatible data collection and management systems.

The value of DEX depends on the equipment and software used by the operator. It should not be assumed that every remote management feature is automatically included with the machine.

Instead, DEX provides a communication capability that may be used with compatible vending systems.

For operators building a more organized vending route, access to machine data can be useful when paired with the right hardware and services.

Cash Payment Capability

Cash remains useful in many vending locations.

This National Vendors snack machine is listed with a 3-tube coin mechanism and a bill validator that accepts $1 bills.

That means customers are not limited to a future card reader installation. The machine is configured to support traditional vending transactions as well.

A location can therefore serve customers who prefer cash while the operator considers whether adding a compatible cashless reader makes sense.

3-Tube Coin Mechanism

The machine is equipped with a 3-tube coin mechanism.

A coin mechanism accepts supported coins and helps manage change during vending transactions.

Keeping the coin mechanism properly stocked with change is an important part of normal route service.

If change levels become too low, some cash transactions may become more difficult to complete. Operators should check the coin mechanism during regular service visits.

Routine inspection also gives the operator a chance to remove dirt or foreign material around the payment area and check for obvious problems.

$1 Bill Acceptance

The installed bill validator is listed as accepting $1 bills.

Bill acceptance makes the machine more convenient than a coin-only vending system. Customers can use a dollar bill instead of carrying the exact amount in coins.

The validator should be kept clean and maintained as part of normal vending machine service.

Worn, damaged, folded, or dirty currency may not always be accepted. That is normal for vending validators and does not always indicate a machine problem.

Approximately 300 to 400 Item Capacity

The National Vendors 157 is listed with a capacity of approximately 300 to 400 items.

Actual capacity will vary.

Large bags of chips take more room than small candy bars. Thick packages may reduce the number of products that fit in a selection. Shelf configuration also affects total capacity.

For this reason, the 300 to 400 item figure should be treated as an approximate machine capacity rather than a guarantee for every product mix.

Even so, the large commercial cabinet gives operators much more stocking flexibility than a small countertop machine.

Why Capacity Matters on a Vending Route

Capacity is about more than the number of products a machine can hold.

It can also affect how an operator plans a route.

A larger machine may allow more inventory to be placed at a location during each service visit. If sales are steady, that may help reduce unnecessary trips compared with a very small machine.

The right service schedule depends on the location.

A busy account may need frequent visits even with a full-size machine. A slower account may go longer between fills.

The goal is to keep popular selections available without carrying too much slow-moving inventory.

Ultra Black Appearance

The Ultra Black styling gives this National Vendors machine a clean commercial appearance.

Black vending equipment works well in many types of indoor locations. It can blend into offices, break rooms, warehouses, apartment common areas, waiting rooms, and other business settings.

The dark cabinet also provides a neutral background for colorful snack packaging.

That can help products stand out when customers look through the front of the machine.

Because this is refurbished equipment, cosmetic appearance can vary from machine to machine. A refurbished machine should not be expected to look identical to a brand-new unit.

Refurbished National Vendors Snack Machine

This National Vendors 157 is sold as a refurbished vending machine.

Refurbished commercial vending equipment can be an attractive option for new operators, established vending routes, businesses, and property managers.

It allows buyers to obtain a full-size commercial machine without automatically moving into the price range of new commercial equipment.

For many operators, this can leave more of the startup budget available for inventory, transportation, card reader equipment, moving costs, insurance, route development, and other business expenses.

Why Consider a Refurbished Snack Vending Machine?

New equipment is not the only way to build a vending route.

Commercial vending machines are made for repeated use. A refurbished machine can provide useful service when it has been properly prepared and is matched to the right location.

Potential Advantages of Refurbished Equipment

  • Lower initial equipment cost compared with many new commercial machines
  • Full-size commercial cabinet
  • Large snack capacity
  • Many product selections
  • Established National Vendors platform
  • MDB electronic control system
  • DEX protocol capability
  • Cash payment equipment
  • Credit card reader capability with compatible equipment
  • Flexible product layout
  • Useful for new or established vending routes

Designed for Commercial Vending

The National Vendors 157 is not a small tabletop candy dispenser.

It is a full-size commercial snack vending machine.

That distinction matters.

Commercial vending equipment is designed around the needs of real vending locations. Operators need inventory capacity. Customers need product variety. Service technicians need access to machine components. Payment systems need to handle repeated transactions.

A full-size machine is designed with these needs in mind.

Ideal Locations for the National Vendors 157

The right vending machine location depends on traffic, customer demand, access, security, power, and other factors.

The National Vendors 157 may be considered for many indoor commercial environments.

Office Buildings

Employees often want a quick snack without leaving the building.

A full-size snack machine can provide chips, candy, cookies, crackers, and other packaged products throughout the workday.

Employee Break Rooms

Break rooms are a natural location for snack vending.

Employees can make a quick purchase during scheduled breaks without waiting in line at a store.

Warehouses

Warehouse employees may work long shifts or schedules that extend beyond normal store hours.

A vending machine can provide on-site access to snacks throughout the day.

Manufacturing Facilities

Factories and production facilities can have large employee populations.

A commercial snack machine may help serve break areas where workers need fast access to packaged food.

Apartment Communities

A snack machine may work in a shared indoor area, laundry room, recreation room, or other approved location.

Property managers should choose a secure area with suitable electrical access and enough space around the machine.

Hotels and Motels

Guests often want snacks outside normal restaurant or store hours.

A vending machine can provide convenient self-service access.

Auto Service Locations

Customers waiting for repairs may appreciate access to snacks.

The machine can be placed in a customer waiting area when space and site conditions are suitable.

Schools and Educational Facilities

Snack vending may be useful in approved educational settings.

Operators and facility managers should follow all local rules, nutritional requirements, and site policies that apply.

Fitness Centers

Gyms may use vending machines for packaged snacks, protein bars, nuts, and other products suited to their customers.

The exact mix should be based on demand at the specific location.

Retail Employee Areas

Large retail businesses often have staff break rooms.

A commercial snack machine can give employees access to food without leaving the property.

Build a Better Snack Mix

A machine with 30 to 40 selections gives an operator many choices.

However, filling every selection with a different product is not always the best strategy.

High-selling products may deserve more than one selection. Slow sellers may need only one.

A good product plan usually develops over time.

Start with Familiar Products

Recognizable snacks can make a good starting point.

Use sales results to learn what customers actually buy rather than relying only on assumptions.

Offer Different Price Points

Product costs vary.

A balanced machine may contain basic snacks as well as larger or premium products, depending on the pricing capabilities and local demand.

Watch Expiration Dates

Do not overload slow-moving selections.

Rotate inventory and check dates during every service visit.

Keep Popular Products Available

An empty selection cannot generate a sale.

When a product repeatedly sells out, consider increasing its inventory or assigning another selection to the same item.

Replace Weak Sellers

If a product sits for too long, try something else.

One advantage of a multi-selection snack machine is the ability to change the menu without replacing the entire machine.

Use Sales Data to Improve the Product Mix

Vending is easier to manage when decisions are based on actual sales.

The National Vendors 157 includes DEX capability. When used with compatible equipment and systems, vending data may help operators understand machine activity.

Operators can also track sales manually.

The important point is to learn which products sell and which do not.

Over time, this information can help create a stronger product mix.

Credit Card Reader Upgrade Potential

Cashless payment has become an important consideration for many vending operators.

The MDB board in this National Vendors 157 makes the machine a better candidate for compatible cashless equipment than older machines without MDB capability.

A compatible reader may add support for card and other electronic payments, depending on the reader and service selected.

Again, the reader itself is not included.

Before ordering cashless equipment, verify the machine configuration and reader requirements.

Costs to Consider When Adding a Card Reader

  • Card reader hardware
  • Installation
  • Activation fees, if applicable
  • Wireless or service fees
  • Transaction processing fees
  • Merchant account requirements
  • Additional compatible hardware, if required

These costs vary by provider and are separate from the vending machine unless specifically stated otherwise.

Plan the Location Before Delivery

A full-size vending machine is large and heavy.

The National Vendors 157 is listed at approximately 72 inches high, 38 inches wide, and 35 inches deep. Its listed weight is approximately 697 pounds.

Measure the complete delivery path before ordering.

Do not measure only the final vending location.

Check the Entire Delivery Route

  • Exterior doors
  • Interior doors
  • Hallways
  • Elevators
  • Stairways
  • Gates
  • Turns and corners
  • Loading areas
  • Floor transitions
  • Final machine location

Also consider door handles, trim, railings, and other objects that can reduce usable clearance.

Choose a Suitable Indoor Location

The machine should be placed on a stable surface in an appropriate indoor commercial setting.

There should be enough space for customers to use the machine comfortably.

Operators also need access for loading, cleaning, collections, and service.

Avoid blocking exits, walkways, electrical panels, fire equipment, or other required access areas.

Always follow building rules and local requirements.

Electrical Planning

Confirm the electrical requirements of the specific machine before installation.

The outlet should be appropriate for the equipment and installation environment.

Avoid unsafe extension cord arrangements.

If you are uncertain about the electrical setup, consult a qualified professional before operating the machine.

Loading the National Vendors 157

Proper loading helps a snack machine operate correctly.

Do not simply place products into the spirals and assume every package will vend the same way.

Step 1: Select the Product

Choose packaged products that fit the available selection.

Step 2: Check Package Size

Make sure the package fits comfortably between the spirals and does not rub excessively against nearby products or dividers.

Step 3: Load Products Consistently

Place each package in a consistent position.

Poorly loaded products can move differently during a vend.

Step 4: Test Vend

Run several test vends before filling the selection completely.

Confirm that the product moves forward and drops correctly.

Step 5: Adjust When Needed

If a product does not vend well, review the spiral size, product position, and selection setup.

Routine Service Helps Protect Reliability

All vending machines require maintenance.

A good service routine can help prevent small issues from becoming larger problems.

Clean the Machine

Wipe down customer contact areas and remove dust, crumbs, and packaging debris.

Keep the delivery area clean.

Inspect the Spirals

Look for bent or damaged spirals.

Confirm that products are loaded correctly.

Check the Payment Area

Inspect the bill validator and coin mechanism.

Keep the surrounding area clean.

Check Product Dates

Rotate inventory and remove expired or damaged products.

Test Several Selections

Periodic test vends can help identify a problem before customers encounter it.

Keep the Machine Presentable

A clean vending machine creates a better impression.

Customers may be more comfortable buying from equipment that looks cared for.

Useful for New Vending Operators

Starting a vending business involves more than buying a machine.

You need locations, products, transportation, payment systems, pricing, service schedules, and a plan for maintenance.

A refurbished National Vendors 157 can provide a practical commercial platform for someone building a route.

Its full-size design provides room to learn which products sell without immediately being limited by a tiny cabinet.

The MDB board also gives the operator a path toward compatible cashless payment equipment.

Useful for Established Vending Routes

The National Vendors 157 is not limited to beginners.

An established operator may also consider this machine when adding a new account, replacing older equipment, or expanding an existing route.

Operators who already use National Vendors equipment may also appreciate working with a familiar commercial vending platform.

Actual parts compatibility varies by model and revision, so part numbers should always be verified before ordering replacement components.

A Good Balance of Traditional and Modern Features

One reason this machine remains useful is its combination of traditional vending hardware and newer electronic capability.

Customers can use cash through the coin mechanism and bill validator.

Operators also have MDB electronics for compatible payment peripherals.

DEX capability adds another useful feature for operators who use compatible vending management systems.

This mix can make the National Vendors 157 a flexible option for many commercial vending environments.

National Vendors 157 Dimensions

The listed dimensions are:

  • Height: 72 inches
  • Width: 38 inches
  • Depth: 35 inches

The listed weight is approximately 697 pounds.

Dimensions and weight are especially important when planning delivery.

Measure carefully before purchasing.

Moving a Full-Size Snack Machine

Commercial vending machines are heavy.

Proper moving equipment and trained personnel should be used.

Do not treat a full-size vending machine like normal household furniture.

Plan the move in advance and consider floor conditions, slopes, thresholds, steps, doorways, and other obstacles.

If you do not have suitable equipment or experience, use a professional vending machine mover.

Plan for Restocking Efficiency

A vending route becomes easier to manage when each stop is organized.

Before arriving at the machine, know which products are likely to be needed.

Keep inventory organized in the service vehicle.

During the visit, check product levels, expiration dates, cash equipment, cleanliness, and machine operation.

A consistent service routine can save time across a larger route.

Product Pricing Strategy

Product prices should be based on your costs and business needs.

Consider wholesale product cost, card processing costs, fuel, labor, location commissions, equipment expense, spoilage, taxes, and other operating expenses that apply to your business.

Do not choose prices based only on what another machine charges.

Different routes can have very different operating costs.

Keep the Machine Full but Avoid Overstocking

An empty machine can lose sales.

However, excessive inventory can create waste if products expire before they sell.

The goal is to find the right balance.

High-volume selections may need deeper inventory. Slow sellers may need fewer units.

Review the machine regularly and adjust your plan.

Use the 30 to 40 Selections Strategically

The large selection count is valuable only when it is used well.

Do not feel that every selection must contain a completely different item.

If one chip variety sells much faster than everything else, using two columns for that product may make more sense than carrying another slow seller.

The same idea applies to candy, cookies, pastries, and other snacks.

Let customer demand guide the layout.

Merchandising Tips for Snack Vending

Good merchandising can make the machine easier to shop.

Keep Similar Products Together

Grouping similar products can help customers find what they want quickly.

Keep Labels Easy to Read

Make sure selection information and pricing are clear.

Avoid Crushed Packages

Damaged products create a poor impression and may not vend correctly.

Keep the Glass Clean

Customers should be able to see the products clearly.

Fill Empty Spaces

A well-stocked machine generally looks more inviting than one with many empty selections.

Refurbished Equipment and Cosmetic Condition

Buyers should remember that refurbished equipment is not the same as factory-new equipment.

The machine has had a previous service life.

Normal cosmetic variation may be present.

This can include minor signs of prior use that do not prevent the machine from performing its intended vending function.

For many buyers, the value of refurbished equipment comes from obtaining commercial vending capability without paying for a brand-new cabinet.

Why the MDB Board Matters for Future Upgrades

Vending technology continues to change.

Payment equipment is one of the areas where operators frequently make upgrades.

A machine equipped with MDB electronics gives the owner a stronger starting point for compatible peripherals.

That does not mean every new device will automatically work.

Compatibility should always be checked.

However, MDB is an important feature when comparing commercial vending machines for a modern route.

Cashless Does Not Mean Cash Has to Disappear

Some vending operators add card readers while keeping the existing coin and bill equipment.

This gives customers more ways to pay.

A person carrying cash can use the traditional payment system. Another customer may prefer an electronic payment method supported by the installed cashless reader.

The National Vendors 157 provides a platform that can support this type of payment flexibility when properly equipped.

Questions to Ask Before Ordering

Before purchasing any commercial vending machine, review your location carefully.

  • Will the machine fit through every doorway?
  • Is the final location indoors and secure?
  • Is suitable electrical service available?
  • Is there enough customer traffic?
  • What snacks are likely to sell?
  • Who will refill and service the machine?
  • How will the machine be moved into place?
  • Do you plan to add a credit card reader?
  • Have you confirmed card reader compatibility?
  • Does the site require insurance or a vending agreement?

Answering these questions before delivery can prevent costly problems later.

Why Product Variety Matters

Customers are more likely to find something they want when a vending machine offers a varied selection.

The 30 to 40 selection range of the National Vendors 157 gives operators room to serve different tastes.

You can offer sweet products, salty products, lighter snacks, and more filling choices in the same machine.

You can also change the mix based on actual sales.

That flexibility is valuable because vending demand is local. A product that sells well in one building may move slowly in another.

Why a Full-Size Machine Can Make Route Service Easier

Travel time is a major part of vending route service.

Every stop takes time. The operator must drive to the location, enter the property, open the machine, load products, collect money, clean the equipment, and perform basic checks.

A larger machine gives the operator more inventory space at each location.

This does not guarantee fewer service visits, but it gives the operator more capacity to work with.

Service frequency can then be adjusted based on actual demand.

Keep Records for Each Machine

Good record keeping can improve vending route management.

Keep track of the machine model, serial information, location, service history, parts replaced, payment equipment, and product performance.

When maintenance is needed later, these records can save time.

They can also help when managing several machines across a larger route.

Preventive Maintenance Is Worth the Time

Waiting until a machine stops working is not always the best maintenance strategy.

Basic preventive care can help identify problems earlier.

Listen for unusual motor sounds. Check selections that appear slow or inconsistent. Inspect payment equipment. Look for loose or damaged parts.

Keep the cabinet and delivery area clean.

Small maintenance tasks can become part of the normal restocking visit.

Keep Common Service Supplies Available

Vending operators often save time by keeping basic service supplies in the route vehicle.

The exact supplies depend on the machines being serviced.

Useful items may include cleaning materials, basic hand tools, product labels, price labels, spare vending components, and machine documentation.

Never replace an electrical or mechanical component unless you know it is compatible with the specific machine.

National Vendors Parts and Service Planning

Commercial vending machines contain many replaceable parts.

Over time, components can wear and may need service.

When ordering replacement parts for a National Vendors machine, identify the model and verify

Why Buy A Refurbished Machine?

Great Returns - Commercial Grade Machines - Affordability


New vs Refurbished

We used to sell new machines as well as reconditioned ones. We no longer sell new, for one main reason.

According to a recent survey of vending operators, about 93 out of 100 potential vending accounts don't generate enough revenue to justify the cost of new equipment. New machines are great if you have high volume accounts, but most people do not have these accounts.

Typical pricing on new "commercial grade" machines:

  • Can drink machines: $6,200–$7,400
  • Snack machines: $6,600–$8,500
  • Cold food machines: $8,900–$11,700

(Priced with mech and validator, typical options, vendor pricing not including sales tax or shipping in some cases.)

As you can see, that's quite high compared to used or refurbished equipment.

Please remember 'anyone and everyone' can call their machines refurbished but what does that really mean? Please see our machine ratings page for what we actually do to our machines. Many of our competitors don't even 'clean or paint the inside' of the machines.

Start small and grow as you can afford it.

Many people start in the vending business without much knowledge, and that can hurt them financially if they're not careful.

All of the machines that we sell are full size, commercial machines. There are many machines that are made that are small, countertop or mechanical coin acceptance. These machines are fine if you are a housewife looking to make a little extra money on the side. We used to sell those type of machines and no longer do. The main reason is that people who were serious about vending would out grow these type of machines in several months.

Small mechanical machines have two main problems:

  • They don't make change or accept dollar bills
  • They "work you to death" — frequent refills for very little payoff

Most hold under 100 products and gross only $40–$50 per full restock, and profit is less than half of that.

A full-size commercial machine, by contrast, usually holds 350 to 600 products and empties out at $250–$500. Since you spend most of your time just driving to the location, you might as well fill 500 products instead of 50.
