Contractor Abrasive Blast Machines:
Rugged, Mobile, Easy to Use and Maintain


Clemco Contractor Blast Machines are tough, versatile, and reliable—which makes sense, because they are built for blasting contractors who need equipment that works as hard as they do. And because contractors can’t be slowed down by unreliable, cumbersome equipment that is difficult to maintain, these machines are mobile, easy to operate, and simple to maintain. They are loaded with standard features that help you get jobs done, such as:

  • An integral, four-wheel, two-axle cart that makes these machines easier to maneuver, even with abrasive in the pot.
  • The cart is constructed from steel-tubing that protects all plumbing, is ergonomically shaped, and doubles as a skid.
  • An integral CPF breathing-air filter directly attaches to the rear of the machines and is protected by the cart’s tubing.
  • Connection points are conveniently located on the front leg of the machines, which simplifies hooking up the blast hose, remote controls, and breathing-air line.

Contractor Blast Machines come with 4-cuft or 6-cuft pressure vessels. The machines are ideal for rental yards and are especially useful for blast and paint contractors, as well as hundreds of other professionals.

Available in Two Sizes: 4 cuft and 6 cuft


  • 4 cuft: Approximately 400 lbs of mineral abrasive.
  • 6 cuft: Approximately 600 lbs of mineral abrasive.

29″ Width

  • Fits through standard doorways.

Integral 4-Wheel Cart

Increases Mobility, Protects Plumbing
and Components

  • Ergonomically designed and made from heavy-duty steel tubing.
  • Operators can easily tilt the four-wheel, two-axle cart onto the back wheels for maneuvering the machines at blast sites, even if a machine has abrasive in the pot.
  • The steel tubing forms a cage that protects plumbing, especially at the weld joints, and components such as the remote control valves.
  • The optional, integral CPF breathing-air filter attaches to the rear of the machine and is protected by the cart.
  • The cart’s tubing doubles as a skid. Operators can pull a Contractor Blast Machine into a truck bed or onto a trailer and leave the machine resting horizontal on the tubing. This placement reduces the truck’s or trailer’s center of gravity.

 1.5″ Remote Controls and 1.25″ Piping

1.25” Piping

  • 50% more air flow than with 1″ piping.

1.5″ Millennium Pneumatic Remote Control Valve

  • Pressing the remote control handle simultaneously actuates the inlet and outlet portions of the valve.
    • Quickly starts and stops—less time waiting and more time blasting.
    • Other systems separately actuate the inlet and outlet functions, which can slow response times.
  • Because the valve has only two moving parts, it is simple to field service with standard tools.

 Functional Front Leg and Handhole


Front Leg with Connection Points

  • Blast-hose, remote-controls, and breathing-air connection points are all easily accessible on the machine’s front leg.
  • A weather-tight storage bin on the top of the front leg can hold the operations manual, paperwork, small parts, and other small items that may be needed in the field.

Large Handhole

  • 8.8″ W x 6.3″ H elliptical shape for easy access to the pot’s interior.
  • Cut to conform to the blast machine’s wall and welded inside and out. This design creates fewer nooks and crannies where abrasive can collect.

 Manual Quantum Metering Valve

Meter All Common Blast Media

  • From coarse steel grit to mineral slags or crushed glass.
  • Just empty the blast machine, pour in the new media, and start blasting—regardless of the application.

Abrasive Flows at 45° into Air Stream

  • The natural way to uniformly mix air and abrasive.
  • Eliminates premature wear found in 90° systems.

For Contractors

  • The valve’s flexibility and durability reduce downtime between jobs that require different blast media.

For Rental Yards

  • Every Contractor Blast Machine is ready to roll out the door regardless of the application.
