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

Clean series 10-AR regulators have fluorine grease, are assembled and inspected in a workshop, and have clean packaging (products are sealed in anti-static double bags after the surface has been blown with clean air).  The 10-AR series has a particle generation grade of 1, and is available with port sizes

Note 2) Option B, G, H are not assembled and supplied loose at the time of shipment. Note 3) Assembly of a bracket and set nuts (10-/21-AR20(K)-B to AR40(K)-B) Including 2 mounting screws for the 10-/21-AR50(K)-B, AR60(K)-B Note 4) The only difference from the standard specifications is the adjusting spring for the regulator. It does not restrict the setting of 0.2 MPa or more.
