The 3030 Savage Direct Pressure Blasting Cabinet was designed to operate using smaller air compressors using 220-volt single-phase electrical power. This is the electrical power found in home garages and commercial boulevard facilities that don’t have access to three phase electrical power to operate large air compressors. The 3030 Savage has the correct abrasive flow controls for the smaller air volumes.
The 3030 Savage is also a constant pressure design that holds the pot pressure until the operator decide it’s time to fill the pot assembly. This results in instant on-off control of the blasting cycle, fast pressure pot re-loading and use less compressed air.
Most abrasives, when using direct pressure, reach maximum impact velocity at a much lower pressure than siphon delivery. Glass beads have a maximum impact velocity of 40 psi when using direct pressure. Harder abrasive like aluminum oxide have a maximum impact velocity of 50 psi. The machine can be shipped with 1/8” nozzle or 3/16” nozzle depending on how much compressed air you have. The 1/8” nozzle uses 12 cfm at 50 psi and the 3/16” nozzle uses 23 cfm at 40 psi. Choose the nozzle size right for your smaller air compressor or have the machine shipped with both sizes.
