Type 340 Regulator

Brand: ControlAir

The Type 340 Series of Instrument Air Regulators are designed to provide clean, accurate air pressure to instruments, valves, and other automatic control equipment in a lightweight, compact housing.

These quality instruments are constructed of durable materials that will provide long lasting corrosion resistance in harsh industrial environments.

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.
