In-line water traps/filters are necessary to separate water and oil from the airflow during the air compression process.

A regulator is combined with the filter to increase or decrease the pressure.
A pressure gauge indicates the set pressure.

Visible arrows are on the outer body of the casing that indicate the direction of installation to
correspond with the direction of airflow.

Drain: Manual

A push-in fitting is located on the drain to allow fluid to drain to a central point via PU tubing (not included).
