Type 300 Instrument Air Filter Regulator Series


code :

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.

OPTIONS - Add proper letter onto end of model number:
**E - Tapped Exhaust: allows captured exhaust. 1/4" NPT port.
F - 5 Micron Filter: standard 40 micron filter is replaced with 5 micron filter for more complete air filtration.
***J - Low Temperature: temperature range -62° to 194° F (-52° C to 90° C).
*K - Knob: to replace square head adjust screw.
N - Non-Relieving: for constant flow or downstream pressure relief applications.
**P - Panel Mount: option allows panel mounting. See dimensional drawing.
S - Stainless Steel Adjust Screw: hexhead stainless steel adjust screw for maximum corrosion resistance.
*T - Tamperproof Cover: prevents casual adjustment of output pressure.
**V - Viton® Elastomers: used where elements in the supply air are particularly destructive to standard Buna-N pintle and diaphragm material.
X - ATEX: 94/9/EC
* Options for Type-300 only.
** Standard features for Type-310 NACE.
*** Low Temperature Option not available for Type-310 NACE
