Perfect for automotive shops and other low-production applications — the DCM-161 automatically removes rust and carbon buildup. The basket holds 2 gallons — up to 25 pounds of brake parts, engine components, or other small hardware. The suction blast system works with most fine-mesh media and requires just 17 cfm of air at 60 psi. Includes door-mounted ZERO automatic gun with a #5 ceramic nozzle and a #4 orifice, a 100-cfm exhaust fan to draw dust into the bag filter, and a manual reset 60-minute timer.
