Series AR-B regulators from SMC 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.
