When the air supply is cut off and
releasing the inlet pressure to the
atmosphere, the residual pressure
release of the outlet side can be ensured
for a safety purpose.

Note 1) Optional parts are not assembled and are supplied loose at the time
of shipment (except options C, D and E).
Note 2) Applicable tubing O.D for auto drain connection should be ø3/8" in
case NPT thread port is chosen.
∗ When more than one specification is required, indicate in alphanumeric order.
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.
Note 5) Without a valve function.
Note 6) For NPT thread type. This product is for overseas use only according to the new
Measurement Law. (The SI unit type is provided for use in Japan.)

Note 1) Assembly includes a bracket and set nuts.
Note 2) in part numbers for a round pressure gauge indicates a
type of connection thread. No indication is necessary for R;
however, indicate N for NPT. Please contact SMC
regarding the connection thread NPT and pressure gauge
supply for PSI unit specifications.
Note 3) Includes one O-ring and 2 mounting screws.
Note 4) Minimum operating pressure: N.O. type–0.1 MPa;
N.C. type–0.1 MPa (AD27) and 0.15 MPa
(AD37/47). Please contact SMC regarding the
specifications for PSI unit and °F.
Note 5)
When “N” is specified in the end of part number of
auto-drain, applicable tubing O.D should be ø3/8".

Note) AW10 comes with a back flow
mechanism as a standard feature.
If the set pressure is not exceeding
0.15 MPa, back flow may not occur.
When a back flow mechanism is
required with a set pressure of less
than 0.15 MPa, please contact SMC.

Note 1) Drain guide is NPT
1/4 (applicable to
AW30K and 40K),
and the exhaust port
for auto-drain comes
with ø3/8" One-touch
fitting (applicable to
AW30K and AW40K).
Note 2) Drain guide is G 1/4
(applicable to AW30K
and AW40K).
Note 1) Set the inlet pressure 0.05 MPa or higher than the set pressure.
Note 2) Pressure gauge connection threads are not required for regulators with a square embedded type
pressure gauge (AW20K to AW40K).
