Note 7) Pressure switch cannot be mounted on the inlet and outlet sides of an ARG with an upward facing handle (optional specification: -Y). Note 1) Wall mount is not available for size 20 regulator with downward facing handle in B combination. Contact SMC when wall mount is needed. Note 2) The number inside ( ) indicates the combination order counted from the inlet side. Note 3) Drain guide is NPT1/8 for ACG20 and NPT1/4 for ACG30 and 40. Auto-drain port is provided with o3.8" One-touch fitting (applicable to ACG30 and 40). Note 4) Drain guide is G1/8 for ACG20 and G1/4 for ACG30 and 40. How to Order Symbol Description Applicable model Note 5) Mounting angle of pressure gauge is G1 only. If other mounting angles are needed, contact SMC. . Possible to change to the optional mounting angles. For details, refer to page 584, “Procedure for replacing or changing the mounting angle of a pressure gauge”.
