Type 330 Air Filter Regulator

Brand: ControlAir

The Type 330 Series of Air Filter Regulator are designed to provide clean, accurate air pressure to instruments, valves, and other automatic control equipment in a lightweight, compact housing.

These quality instruments are constructed of durable materials that will provide long lasting corrosion resistance in harsh industrial environments. 

The Type 330 Filter Regulator is designed for use in systems that require clean, accurate instrument air, the Type-330 provides pressure regulation and filtration in an integral compact package. 

Available in ¼" NPT porting for normal operation and ½" NPT porting for high flow capacity requirements. 

The Type 330 Filter Regulator with Automatic Drain automatically flushes out condensate waste liquid when a change in air flow occurs or when the supply pressure is reduced. 

The low maintenance Automatic Drain helps prolong the life of the regulator and filter by preventing corrosion on the bottom of the regulator and reducing the load of the filter.
