The Type 300 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 AFR is a quality unit that is ideal as an economical alternative for control of process applications. For NACE MR-01-75 complaint option, see our Type 310 air filter regulator.
Options and features (see specifications tab for full list):
- 1/4” ports
- ATEX certifications
- Low Temperature option: down to -62°F (-52 °C)
