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. .

How we test our used compressors prior to reselling them

We run all our used compressors for 2+ hours and do cubic feet air flow tests prior to shipping. We make repairs needed for proper compressor operation. Cylinder valves are inspected and replaced when needed, purifications towers are internally and externally inspected for pitting and cracks, oil is changed with fresh food grade high temperature synthetic oil and new replacement purification filters are installed. We strive not to have follow up repairs after unit delivery.
