The old AW10 to 60 series (2 digits: AW□□) was discontinued in December 2014.
It was replaced with the AW10-A to AW40-A series.
The features of AW-A series filter regulators are as follows. ① The flow rate characteristics (reduced pressure drop) have been improved. ② The product has been whitened. ③ A backflow function has been added. (When the inlet pressure is removed, residual pressure can be exhausted to the inlet side. However, it may not be exhausted when the set pressure is 0.15 MPa or less.)
The main differences/similarities between old AW and AW-A series filter regulators are as follows. ① The set pressure range differs. (Old AW: 0.05 to 0.8 5MPa, AW-A: 0.05 to 0.7 MPa) ② The dimensions between faces and the bracket mounting dimensions are the same. ③ For AW-A series filter regulators, only the round type pressure gauge is available. ④ Old panel mounted AW and AW-A series filter regulators are not interchangeable.
When replacing an old AW series filter regulator with the following conditions (A to E), select a filter regulator from the AW20-B to AW60-B series. (A) The set pressure is 0.7 to 0.85 MPa. (B) A square embedded type pressure gauge or digital pressure gauge are required. (C) The same dimensions for panel mounting are required. (D) A regulator with a backflow function is required (E) The product was an AW60.
Note 1) When only the AW series filter regulator of an old AC series modular F.R.L. unit (2 digits: AC□□) is replaced, the old spacer cannot be used with an AW-A series regulator. Replace the AW with an AW-A with a new spacer or with an AW-B.
Note 2) Check separately for the replacement of old special order AW series filter regulators.
