The Industrial Air 15 gallon air compressor offers 5.1 SCFM at 90 PSI with an industry leading 225 max PSI. 225 max PSI gives you the power and performance of a larger compressor in a smaller unit providing longer air tool run times before the compressor has to refill. This equates to more work done and greater project efficiency. The 8 inch wheels and slim compact design offer greater portability and ease of storage in your shop or garage.
