300 Series Pressure Regulator

Brand: ControlAir

The Type-300 Instrument Air Filter Regulator is designed to provide clean, accurate air pressure to instruments, valves, and other automatic control equipment.

This filter regulator has been proven to provide accurate operating characteristics under variable conditions. Durable materials and a standard epoxy paint finish provide long lasting corrosion resistance in harsh industrial environments.

The Type-300 is a quality unit that is ideal as an economical alternative for control of process applications. 

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.
Features
  • Corrosion-Resistant and NACE Compliant Construction
    • Types 300 and 320 feature Aluminum die-castings, finished with irridite and baked epoxy. Materials in the Type 310 meet NACE MR-01-75 requirements. 
  • Depth Filter
    • Units come equipped with high capacity 40 micron depth filter housed in dripwell 
  • Two Outlet Connections
    • Provides piping versatility
