20 Cuft Classic Blast Machines

High-performance, versatile blast cleaning system removes contamination, corrosion, mill scale, and coatings from most surfaces. Produces a uniform surface texture, and creates a surface profile to increase bonding for coatings.

Model 3680 holds 20 cubic feet of abrasive.

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).
• Minimum of 50 psi needed to close the pop-up valve and pressurize the blast machine.
• OSHA-required remote control system that interrupts blasting if operator should lose control of the nozzle when blast machine is pressurized.
• 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 www.cganet.com).
• 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.

Advantages

• Stationary industrial-quality blast machines manufactured to ASME code.
• 1-1/4-inch piping allows up to 50 percent more air flow when compared with 1-inch piping.
• Industrial-quality valves, piping and fittings designed to maximize air flow and minimize energy required to operate the system.
• FSV abrasive metering valve maintains smooth, consistent, adjustable media flow.
