List Updated 4/21/2017

Rental HP breathing air compressors for providing CGA grade E breathing air for human consumption or other uses. We offer 5000 PSI rental air compressors, with various flow rates of 9 to 75 CFM output. Our rental compressors are powered by electric and/or diesel motors.

Used HP breathing air compressors, used HP compressors, used air compressors and used SCUBA compressors are available from American Airworks. 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, Mako compressors, Eagle compressors, Scott compressors and occassionally Airworks compressors.

We buy used fire department compressors at times. Email us your department's compressor low resolution pictures, hours on unit, electrical specifications and compressor specifications, usually, found on a metal plate on the chassis.

We sell new and used ISO air cascade cylinders below....see here!

How we test our used compressors prior to reselling them

We run all our used compressors for 2-4+ 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.
