Jenny 2(W5B)-120

Jenny 2(W5B)-120 is a 10 HP single-stage oil-lubricated reciprocating air compressor delivering 42 SCFM at 100 PSI maximum on a 120-gallon tank. Wired for 120 V single-phase, this industrial unit weighs 1,130 lbs and is priced at approximately $8,699. The Jenny 2W series is a long-established workhorse in industrial and contractor markets, valued for robust cast-iron construction and serviceability. The 120-gallon receiver provides substantial storage for intermittent high-demand applications. Note: single-stage design at 100 PSI max makes it suitable for general shop tools but not for high-pressure applications requiring 150+ PSI. Key gaps: duty-cycle rating, amperage draw, and OEM primary-source datasheet not yet located.
