Note 1) Option B, G, H, M are not assembled and supplied loose at the time of shipment.
Note 2) Assembly of a bracket and set nuts
Note 3) Only for the AR20-A to 40-A
Note 4) When the pressure gauge is attached, a 1.0 MPa pressure gauge will be fi tted for standard (0.7 MPa) type. 0.4 MPa pressure gauge for 0.2 MPa type (1.0
MPa pressure gauge only for the AR10-A).
Note 5) Pressure can be set higher than the specifi cation pressure in some cases, but use pressure within the specifi cation range.
Note 6) For pipe thread type: NPT
Cannot be used with M: Round pressure gauge (with colour zone). Available by request for special.
