Schulz 932.9339-0 is a 5 HP two-stage piston air compressor delivering 20 SCFM on an 80-gallon tank, wired for 230V single-phase. The two-stage cast-iron simplex pump delivers improved volumetric efficiency and reduced heat buildup relative to single-stage designs in the same horsepower class. The 80-gallon horizontal receiver supports sustained shop operations — impact tools, air ratchets, blow guns, and light spray work — without excessive compressor cycling. Schulz builds this line at its ISO 9001-certified Joinville, Brazil plant. The 932.9339-0 is a variant in the 9-series reciprocating line; differentiation from 932.9345-0 not yet confirmed in catalog. Key gaps: rated maximum PSI not in catalog; OEM datasheet URL not retrieved; weight and decibel rating not confirmed.
