NANPU 3/4" NPT Air Compressor Filter Dryer Regulator, 3-Stage, Manual Drain — Open-Box, 36% Off

DRY, OIL-FREE AIR THAT PROTECTS YOUR WORK — Strips water, oil and moisture from compressed air to help prevent paint fisheyes, contaminated plasma cuts, rusty air lines and water damage to pneumatic tools — for cleaner finishes and less rework.

STAGE 1 – AIR FILTER + REGULATOR, HIGH-PRESSURE RATED — Operates across a wide 7–215 psi range; a 5-micron element drops out bulk liquid water, oil and rust/debris while the gauge regulator holds steady output for a consistent spray pattern and stable tools.

STAGE 2 – 0.01-MICRON COALESCING FILTER — Captures 99.998% of the ultra-fine oil aerosols and sub-micron moisture that slip past Stage 1 — the contamination that causes paint blemishes and pitted plasma cuts; a pop-up indicator shows when to change the element.

STAGE 3 – DESICCANT DRYER, NO DRAIN NEEDED — Color-indicating beads absorb the last of the water vapor for truly dry air with no liquid to drain; the beads turn blue→pink when spent, so you simply refill or regenerate them.

INDUSTRIAL-GRADE, BUILT FOR THE SHOP — 3/4" NPT ports, 141 CFM (4000 L/min) flow, heavy metal bowls with sight glass and wall-mount bracket; ideal for HVLP spray guns, automotive painting, plasma cutters, sandblasters and air tools in busy garages and shops. Includes 2× 5μm + 2× 0.01μm elements, 4× desiccant bags (3.5oz / 100g), 2× 3/4" NPT fittings and thread seal tape.

NANPU's 3-stage compressed air dryer, filter regulator and water/oil separator delivers clean, dry, oil-free air for spray painting, plasma cutting, sandblasting and air tools. Moisture, oil and rust in a compressed air line cause paint fisheyes, contaminated plasma cuts and water damage to pneumatic tools — this air drying system removes all three before they reach your equipment. Stage 1 pairs a 5-micron air filter with a pressure regulator and gauge, dropping out bulk liquid water and oil and trapping rust and debris while holding a steady, adjustable 7-215 psi. Stage 2 is a 0.01-micron coalescing filter that captures 99.998% of the ultra-fine oil aerosols and sub-micron moisture ordinary filters miss, with a pop-up indicator that shows when to change the element. Stage 3 is a desiccant dryer with color-indicating beads (blue turns pink when spent) that remove the remaining water vapor for truly dry air. Built for the shop with 3/4" NPT ports, 141 CFM (4000 L/min) flow, heavy metal bowls with sight glass, a manual drain and a wall-mount bracket. Ideal for HVLP spray guns, automotive painting, paint booths, plasma cutters, sandblasters, airbrushes and pneumatic tools in garages and professional shops. Includes 2 x 5-micron elements, 2 x 0.01-micron elements, 4 x desiccant bags, 2 x 3/4" NPT fittings and thread seal tape.
