W4000-03-G3/8" High-Flow Heavy-Duty Air Filter Regulator AIRMIXS
The AIRMIXS W4000-03-G3/8" Air Filter Regulator is a heavy-duty, high-flow 2-in-1 air preparation unit engineered for main shop air lines, heavy automation machinery, and demanding industrial pneumatic systems. Featuring G 3/8" female thread ports in an expanded 4000-series body frame, this unit combines particle/moisture filtration and stable downstream pressure control into a single robust assembly.
Constructed with a heavy-duty die-cast aluminum alloy housing and a high-capacity polycarbonate bowl protected by an integrated metal guard, it efficiently strips out water condensate, oil aerosols, and rust particles. The ergonomic top adjustment knob features a push-to-lock detent mechanism—pull up to set the working pressure, then press down to lock it securely against heavy machinery vibration.
