Product Detail:
Type M1R
The Type M1R Miniature Air Regulator is a compact, low cost regulator, which operates in output pressure ranges up to 120 psi, with a maximum supply pressure of 145 psi. The Type M1R is available in 1/8" and 1/4 " NPT port sizes. With a flow of up to 40 SCFM and low droop the M1R provides the features of a large regulator in a small package.

TYPE M2R
The Type M2R Air Regulator is a mid-sized version of the M1R Miniature Air Regulator. Like the M1R this is a low cost regulator with output ranges up to 120 psig with a maximum supply pressure of 145 psig. The M2R is available in 1/4 ", 3/8 ", or 1/2 " NPT port size. The Type M2R can provide flow rates to 90 SCFM.
