Arrow Pneumatics High-Flow Air Pressure Regulator — Relieving, 5–125 PSI
The Arrow Pneumatics High-Flow Series air pressure regulator delivers precise, stable downstream pressure at high flow rates — built for compressed-air mains, high-demand tools, and industrial drops where standard regulators choke. A relieving piston design and micro-finished brass seat prevent downstream pressure creep, while hard epoxy corrosion protection stands up to demanding shop environments.
