Rated for 175 CFM, it is built for high-demand industrial air systems, large pneumatic tools, and main-line air conditioning where smaller modular FRLs can't keep up. Both the filter and lubricator use rugged 29 oz metal bowls with sight glasses, and an air gauge is included.\u003c\/p\u003e\n\u003ch3\u003eKey specifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003ePort size: 1\" NPT\u003c\/li\u003e\n\u003cli\u003eMax flow: 175 CFM\u003c\/li\u003e\n\u003cli\u003eStage 1 — Particulate filter: 40 micron sintered bronze element\u003c\/li\u003e\n\u003cli\u003eStage 2 — Regulator: standard relieving, with pressure gauge included\u003c\/li\u003e\n\u003cli\u003eStage 3 — Lubricator: oil-fog lubricator\u003c\/li\u003e\n\u003cli\u003eBowls: 29 oz metal bowls with sight glass (both filter and lubricator)\u003c\/li\u003e\n\u003cli\u003eTamper-resistant, three-position adjusting knobs\u003c\/li\u003e\n\u003cli\u003eApprox. dimensions: 15-7\/8\" W x 7-7\/8\" H\u003c\/li\u003e\n\u003cli\u003eApprox. weight: 11.8 lbs\u003c\/li\u003e\n\u003cli\u003eOptional mounting bracket: ACA-7 (qty 2 required)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eConfigurations\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandard, Manual Drain (7-125 PSI)\u003c\/strong\u003e — twist\/manual drain (SKU N3548W)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAuto Drain (7-125 PSI)\u003c\/strong\u003e — automatic float drain for hands-free condensate removal (SKU N3548FW)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHigh Pressure (10-250 PSI)\u003c\/strong\u003e — high-pressure regulator range, manual drain (SKU N3548HW)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eTypical applications\u003c\/h3\u003e\n\u003cp\u003eIdeal for high-volume shop air systems, large air tools and impact equipment, paint and blast operations, production lines, and any application that needs clean, regulated, lubricated air at high flow.
