Schulz 932.7452-P-460/3 – 20 HP 120-Gallon Air Compressor

The Schulz P20120HLV80BR (part 932.7452-P) is a 20 HP two-stage cast-iron reciprocating air compressor delivering 58.4 SCFM at 175 PSI on a 120-gallon horizontal tank, wired for 208-230/460V three-phase power. The pump is splash-lubricated using Schulz SG-TM 30 semi-synthetic compressor oil. Schulz’s L-Series industrial reciprocating units target heavy-duty intermittent shop and light-industrial air at three-phase facilities, supporting production tools, sandblasting, and plant air with two-stage cast-iron construction for sustained pressure build. Key gaps: duty cycle percentage, pump RPM, noise level (dB), and dimensional/weight specs not confirmed from primary manufacturer documentation.
