Controlair Type 300 Instrument Air Filter Regulator

The Type-310 NACE Filter Regulator incorporates all of the operating features of the Type-300 filter regulator, but is constructed of materials that meet NACE specification #MR-01-75 for sulfide stress cracking. Designed specifically for corrosive sour gas environments, the Type-310 NACE is ideal for oil field applications.


The Type-320 Filter unit is a 40-micron depth filter that removes dirt, moisture and other particles from air and gas lines. Robustly constructed of die-cast aluminum with a baked epoxy finish, this unit stands up in corrosive operating conditions. This filter is an economical alternative for air supply line applications that don’t require a pressure reducing regulator.
