6 Cuft Contractor Blast Machines

High-performance blast cleaning system removes corrosion, mill scale, and coatings from most surfaces. Produces a uniform surface texture, and creates a surface profile to increase bonding for coatings. See related literature for additional applications. Machine holds 6 cubic feet of abrasive for up to 30 minutes of continuous blasting at 100 psi with standard No. 6 nozzle (3/8-inch orifice).

Requirements for Operation
These items are required but not included with this equipment:

  • Clean, dry, compressed air of sufficient volume to maintain desired pressure at the nozzle. Refer to Air Consumption Chart in Blast Off 2 booklet (publication stock no. 09294).
  • Maximum working pressure 150 psi
  • Minimum pressure 30 psi needed to operate OSHA-required remote control valves
  • NIOSH-approved, type CE, supplied-air respirator.
  • Grade D breathing-air supply as defined by Compressed Gas Association Commodity Specification: G-7.1 (Refer to
  • Abrasive blast media specifically marketed for abrasive blasting and appropriate for your application.
  • Appropriate blast suit, work boots, hearing and eye protection.

Description of Operation
The operator controls blasting from a remote control handle at the nozzle. Pressing the handle starts blasting; releasing it stops blasting. The blast machine contains abrasive and meters it into the compressed air stream.


  • Four-wheel integral cart for ease of moving.
  • Rated for 150-psi maximum working pressure.
  • 1-1/2-inch Millennium valve provides unrestricted air flow.
  • Quantum metering valve maintains smooth, consistent flow, adjustment knob allows precise control of media flow.
  • 29-inch width fits through standard doorways.
  • 1-1/4-inch piping allows up to 50 percent increase in air flow, when compared to standard 1-inch piping
  • Robust handles act as skid for loading machine into pickup or trailer and protect valves and piping from damage.
  • Central hookup point for blast hose and remote controls.
  • Weather-resistant storage area holds manuals, paperwork and small parts.
