For the part numbers of standard AR-A, AR-B, and AR-D series regulator replacement parts, refer to the operation manuals of each AR series.
The operation manual also contains replacement procedures and exploded views.
Note) Check whether or not the old AR** series parts can still be ordered.

The refreshed AR series with 2 digits and a “B” suffix (AR40-□□-B) was released in May 2012. And the new design AR series with 2 digits and a “D” suffix (AR40-□□-D) was released in October 2019.
AR10-A: Rc1/16
AR20-A to AR40-A, AR20(K)-B to AR60(K)-B, and AR20(K)-D to AR40(K)-D: Rc1/8
Old AR10: Rc1/16
Old AR20(K) to AR30(K): Rc1/8
Old AR40(K) to AR60(K): Rc1/4
Old AR1000: Rc1/16
Old AR2000 to AR3000: Rc1/8
Old AR4000 to AR6000: Rc1/4
The AR20K-B to AR60K-B and the AR20K-D to AR40K-D are regulators with a backflow function.
For example, if you want to install a regulator between a valve and a cylinder, select a regulator with a backflow function for the smooth flow of the cylinder return side compressed air to the regulator.
The second refreshed AC series (2 digits and a “B” suffix: AC□□-□□-B) was released in May 2014. And the third refreshed AC series (2 digits and a “D” suffix: AC□□-□□-D) was released in October 2019.
