Question by: Hank M on May 25, 2025, 9:45 AM

got a 1/2 inch air line in the shop. will this regulator keep up, or is 215 scfm kinda wishful thinking

Answer by: Customer Support on May 27, 2025, 8:53 AM

For higher-demand air tools and general pneumatic equipment, the 215 SCFM flow rating is the capacity reference for this regulator, and it matches up well with the 1/2 NPT port size. It is built to control downstream pressure in the 0 to 140 PSI adjustment range while handling up to 250 psi inlet pressure.

Question by: Donna K on Jan 3, 2026, 2:54 PM

What size are the ports on this regulator?

Answer by: Customer Support on Jan 5, 2026, 6:46 AM

It's got 1/2 NPT ports, which should be pretty standard for hooking up to your air lines.
