• Clean room compliant (10-ARP).
• Copper-free, fluorine-free (20-ARP).
• Clean room compliant, copper-free, fluorine-free, silicon-free (21-ARP).
• With the backflow function it incorporates a mechanism to exhaust the air pressure in
the outlet side reliably and quickly.
Example 2)
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 en-
sured for a safety purpose.
Example 1)
When the pressure in the rear and
the front of the cylinder differs:

Note 1) Options B, G, H are shipped together, (but not assembled).
Note 2) Set nut is included for bracket.
Note 3) When choosing with H (panel mount), the installation space for the lead
wires will not be secured. In this case, select “wiring top entry” for the lead
wire entry. (Select “wiring bottom entry” when the semi-standard Y is chosen
simultaneously.)
Note 4) The only difference from the standard specifications is the pressure
regulator spring.
It does not restrict the setting of 0.2 MPa/0.6 MPa or more.
When the pressure gauge is attached, a 0.2 MPa pressure gauge for a
0.2 MPa setting will be fitted, and a 0.7 MPa pressure gauge for a 0.6 MPa
setting will be fitted.
Note 5) For thread type: NPT. This product is for overseas use only according to the
new Measurement Law. (The SI unit type is provided for use in Japan.) The
digital pressure switch will be equipped with the unit conversion function,
setting to psi initially.
Note 6) For options: E1, E2, E3, E4. This product is for overseas use only according
to the new Measurement Law. (The SI unit is provided for use in Japan.)
