We're running 3/8 NPT lines on a mid-size pneumatic setup and need a regulator that'll keep pressure steady through the whole shift. This unit handle that kind of continuous use at the 179 SCFM rating?
Question by: Ronnie A on Aug 25, 2025, 6:08 AM
For mid-range pneumatic equipment on 3/8 NPT lines, the flow capacity and port size on this regulator line up well with that kind of application. The 179 SCFM rating reflects what the unit can move at full capacity, and the relieving design means if downstream pressure creeps up past your set point, it vents automatically rather than letting pressure build unchecked. Inlet pressure can go up to 250 PSI, and the adjustable spring range runs 0 to 140 PSI on the downstream side, so you've got good headroom to dial in whatever your equipment calls for.
