California Air Tools AUX20S 20 Gallon Portable Auxiliary Air Tank

California Air Tools AUX20S is a portable auxiliary air tank designed to store compressed air and deliver it where a fixed compressor is not readily accessible. It is intended for applications requiring a larger reserve of air for intermittent or extended use.

The 20-gallon steel tank provides increased storage capacity, allowing longer operation between refills compared to smaller auxiliary tanks. This makes it suitable for tasks such as spray applications, tire inflation, and running pneumatic tools for short periods.

The tank can be filled through an air compressor using industrial quick-connect fittings or through the integrated Schrader valve using standard tire inflation equipment. This dual-fill approach allows flexibility depending on available air sources.

A pressure gauge is included for monitoring tank pressure during operation. A manual ball drain valve allows removal of condensed moisture after use to help maintain internal tank condition.

The unit is equipped with both male and female 1/4" industrial quick-connect fittings for direct connection to compressors and tools. An air control valve allows adjustment of airflow, and a 48" air hose with tire chuck is included for immediate use.
