Used HP breathing air compressors, We receive used air compressors, mostly from fire departments, that have upgraded to newer larger units. Historically fire departments use their compressors very little and see regular preventative maintenance. Our used high pressure compressor inventory consists of Bauer compressors mostly and occasionally other used HP breathing air compressors.

Rental air compressors available. We lease high pressure industrial air compressors or breathing air compressors for human consumption and other uses. We offer 5000 PSI leased compressors, with various flow rates. Our rental compressors are powered by electric or diesel motors. .
