List Updated 1/20/2015

Used 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 pictures, hours on unit, electrical specifications and purification specifications and low resolution pictures. Usually, found on a metal plate on the chassis. We'll get back to you with an offer to purchase if it meets our requirements and needs.

Rental HP breathing air compressors for providing CGA grade E breathing air for human consumption or other uses. We offer some 5000 PSI rental air compressors, with various flow rates of 9 to 30 CFM output. Our rental compressors are powered by electric and diesel motors.
