The VIAIR 450P Automatic Function Portable Air Compressor is the only 100-percent duty cycle portable compressor on the market, and can run for extended periods of time depending on your environment. Its automatic pressure regulation system is designed to maintain an internal tank pressure of 145 PSI by cycling power to the compressor motor. This compressor is also equipped with a detachable gas-station-style inflation gun, which allows you to easily fill tires with a simple squeeze of the handle. This inflation gun can also show current tire pressure, so you don't need an additional pressure gauge.
