    Portable compressors are typically used to inflate tires, but can also be used to portably pressurize other air receptacles. With portable air compressors ranging in maximum working pressure from 100 PSI to 150 PSI and maximum CFM ratings ranging from 1.27 CFM to 3.00 CFM, there is a VIAIR portable compressor to suit virtually every need. VIAIR portable compressors (except automatic models) are shipped complete with an open-ended (free-flowing) air delivery hose with a quick-connect coupling, a pressure gauge, an air filter element with replaceable air filtration media, a vibration-resistant sand tray, and a deluxe carry bag for simple stowage and increased portability. Automatic models work with closed-ended hoses, similar to hoses used with a typical air tank.
