Aro R37351-100 Air Regulator
The Aro R37351-100 is a heavy-duty compressed air regulator built for industrial pneumatic systems. It features a 3/4 inch NPT female inlet and outlet with an aluminum body and acetal adjustment knob. The unit delivers a maximum flow rate of 210 cfm at up to 250 psi operating pressure.
Suited for high-flow air lines needing precise
This regulator fits main air lines and heavy-duty tool runs where consistent downstream pressure matters. It is not for systems requiring an integrated pressure gauge or installations limited to lower flow capacities.
Handles 210 cfm at 250 psi
The Series 2000 design provides ample headroom for demanding shop compressors and multiple tool stations. Flow demand beyond 210 cfm or pressures above 250 psi will exceed its rated limits.

Questions about this item
What size and thread type does my existing air line need for the 3/4 in NPT ports?
The regulator has 3/4 in NPT female threads on both inlet and outlet, so your supply hose and downstream line must match that size and thread standard.
Will the 250 psi maximum operating pressure work with my older compressor that runs at lower pressure?
Yes, the unit handles up to 250 psi, so it will regulate safely at any lower pressure your compressor delivers.
How can I confirm the regulator is holding the set pressure after installation?
Install a separate gauge downstream; when the knob is adjusted, the gauge should hold steady at the chosen setting while air flows up to 210 cfm.
