Aro-Flo Series Air Line Regulator, 1/4 NPT Ports, 0-140 PSI PSI Spring Range, 86 SCFM Flow Rating

With 1/4 NPT ports, it matches common 1/4 inch NPT air line hydraulic connections. The standard adjustment spring range on this model is 0 to 140 PSI for downstream pressure control.

For typical garage air compressor setups, this regulator should work just fine, given its 1/4 NPT ports and 86 SCFM flow rating. It’s designed to handle the pressure and flow demands of most home shop pneumatic tools.

At 86 SCFM through 1/4 NPT ports, this unit holds up well for mid-range pneumatic equipment without starving the downstream side. Inlet pressure can run up to 250 PSI, and the spring range covers 0 to 140 PSI, which fits most general shop and production line applications without needing a specialty spring swap. If your tools fall within that pressure band, you're in good shape with this one.
