Instrument Air Filter Regulators

The economical instrument air filter regulators provide clean and accurate air pressure to instruments, valves, and other automatic control equipment.

Category:

The Type 300/330/335/340/345 series of Instrument air filter regulators in lightweight & compact housing are designed to provide clean and accurate air pressure to instruments, valves and other automatic control equipment.

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-310 filter regulator incorporates all of the operating features of the Type-300 filter regulator, but is constructed of materials that meet the requirement for sulphide stress cracking. The Type-320 Filter unit is a 40-micron depth filter that removes dirt, moisture and other particles from air and gas lines.

The Type-330 filter regulator with automatic drain, flushes out condensate waste liquid automatically when a change in air flow occurs or when the supply pressure is reduced. The low maintenance automatic drain helps increase the life of the regulator and filter by preventing corrosion on the bottom of regulator & reducing the load of the filter.

The Type-340 Regulator is designed to provide accurate, constant control under variable flow rates and supply pressure. Compact and lightweight housing allows this unit to be mounted in applications where space is limited. Its durable construction withstands long term installation in harsh environments.

The Type-345 filter unit is a 40-micron depth filter that removes dirt, moisture and other particles from air and gas lines.
