California Air Tools AUX05S 5 Gallon Portable Auxiliary Air Tank

California Air Tools AUX05S is a portable auxiliary air tank designed to store compressed air and deliver it where a fixed compressor is not immediately available. It is suited for short-duration applications such as tire inflation, light spraying, and quick service tasks.

The 5-gallon steel tank provides increased air capacity compared to smaller portable tanks, allowing longer use between refills. This makes it useful for maintaining consistent pressure during intermittent tool use.

The tank can be filled using a standard air compressor through its industrial quick-connect fittings or by using the integrated Schrader valve with a service station air source. This dual-fill capability allows flexibility depending on available equipment.

A built-in pressure gauge provides real-time monitoring of tank pressure, while a manual ball drain valve allows moisture to be released after use to maintain tank condition.

The unit includes both male and female 1/4" industrial quick-connect fittings for direct connection to compressors and air tools. A 48" air hose and tire chuck are included for immediate use.
