Note 1) Option B, G, H are not assembled and supplied loose at the time of shipment.

Note 2) Assembly includes a bracket and set nuts (AR25 to AR40)

Includes 2 mounting screws for the AR50 and AR60

Note 3) Mounting thread for pressure gauge: 1/8 for the AR25 to AR30; 1/4 for the

AR40 to AR60. Pressure gauge type: G43

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. When the

pressure gauge is attached, a 0.2 MPa pressure gauge 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.)

w High Pressure

Strong materials are used in the manufacturing of air filters inten-

ded for high pressure operation. Also, construction modification

allows a wider regulating pressure range.

Note 1) The AR10 type comes with a backflow function as a standard feature. (K is not

available.) When using the AR10 type as w/ backflow function, backflow may

not occur with the set pressure 0.15 MPa or less. Please set the inlet pressure

to at least 0.05 MPa higher than the set pressure.

Note 2) Option B, G and H are not assembled and supplied loose at the time of

shipment.

Note 3) Assembly of a bracket and set nuts (AR10, AR20(K) to AR40(K))

Includes 2 mounting screws for the AR50(K), AR60(K)

Note 4) When choosing with H (panel mount), the installation space for lead wires will

not be secured. In this case, select “wiring top entry” for the electrical entry.

(Select “wiring bottom entry” when the semi-standard Y is chosen simulta

neously.)

Note 5) For thread type: M5 and 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.)
