Schulz 970.3891-0

Schulz 970.3891-0 (SRP-3008 Compact-3) is a 7.5 HP oil-injected rotary screw air compressor delivering 27 CFM at 125 PSI on a 60-gallon horizontal tank, rated for 100% continuous duty. The enclosed-cabinet screw design runs cooler and quieter than a comparable piston unit and supplies steady air without the cycling of a reciprocating compressor. It weighs about 445 lb and is controlled by the CONTROL-123-E-NET microprocessor. Well suited to small machine shops, body shops, and continuous-operation cells needing dependable screw-compressor air.
