Precautions
Warning
1. Residual pressure release (outlet
pressure release) is not completed by
releasing inlet pressure. To release
residual pressure, use a filter regulator
with a back flow mechanism.

Maintenance
Warning
1. Replace the element every 2 years or
when the pressure drop becomes 0.1
MPa, whichever comes first, to prevent
damage to the element.
Warning
1. Set the regulator while checking the
displayed values of the inlet and outlet
pressure gauges. Turning the knob
excessively can cause damage to the
internal parts.
2. The pressure gauge indicated with
regulators for 0.02 to 0.2 MPa setting is
for 0.2 MPa use only. Exceeding 0.2
MPa of pressure can damage the
gauge.
3. Do not use tools on the pressure
regulator knob as this may cause
damage. It must be operated manually.
Caution
1. Be sure to unlock the knob before
adjusting the pressure and lock it after
setting the pressure.
Failure to follow this procedure can
cause damage to the knob and the
outlet pressure may fluctuate.
• Pull the pressure regulator knob to
unlock. (You can visually verify this
with the “orange mark” that appears in
the gap.)
• Push the pressure regulator knob to
lock. When the knob is not easily
locked, turn it left and right a little and
then push it (when the knob is locked,
the “orange mark” will disappear).

Note 1) Pressure gauge connection threads are not required for regulators with a square embedded type pressure gauge (AW20 to AW40).
Note 2) Use a bushing (part no: 131368) when connecting R 1/8 pressure gauge to R 1/16 gauge port.
Note 3) Not applicable to AW10.

Accessory Part No.
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 supply of the pressure gauge for PSI unit specifications.
Note 3) For 1 MPa.
Note 4) Includes one O-ring and 2 mounting screws.
Note 5) Minimum operating pressure: N.O. type–0.1 MPa; N.C. type–0.1 MPa (AD17/27) and 0.15 MPa (AD37/47). Please contact SMC regarding the
specifications for PSI unit and °F.
Note 6) When “N” is specified in the end of part number of auto-drain, applicable tubing O.D should be ø3/8".
