Special applications include (10-) clean room compliant, (20-)copper-free, fluorine-free, and (21-) clean room compliant, copper-free, fluorine-free and silicon-free.Direct operated precision regulator, Sensitivity: within 0.2%F.S., 3 types of set pressure allow more freedom in designing a circuit, Repeatability: within ±1%F.S., Backflow function available REGULATOR, PRECISION.

Cost effective and clean looking, series AR regulators offer various pressure range settings to accommodate most applications. The locking adjustment knob prevents accidental setting changes. The modular design of the AR series connects with other SMC air preparation equipment.Modular type regulator, Optional embedded pressure gauge , Available with built-in backflow mechanism , Knob is made
