AR20(*)-B to AR60(*)-B, Regulator & Regulator w/Backflow Function

Air Regulator Series AR-B have been updated to the new urban white base color for a clean modern look. The AR-B series has a maximum set pressure of 125 psi and offers embedded gauge and pressure switch options not found in the AR-A while maintaining panel mounting interchangeability with the previous AR models. The locking adjustment knob prevents accidental setting changes. Options include a mounting bracket and set nuts for panel mounting. The modular design of the AR-B series connects with other SMC air preparation equipment of similar size. The new AR-B is available in six body sizes with piping from 1/8" to 1" in Rc, NPT and G thread.

The AR-B series will end production in March 2025. -- Please select the AR-D series for new applications
