Note 6) When more than one attachment is required, order in
alphabetical order.
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
ø3.8" One-touch fitting (applicable to ACG30 and
40).
Note 4) Drain guide is G1/8 for ACG20 and G1/4 for
ACG30 and 40.

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 the back of page 6, “Procedure for replacing or
changing the mounting angle of a pressure gauge”.
When more than one specification is required, indicate in ascending alphanumeric
order.
