14 sold in last 24 hours
- 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 30–175 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 — 1/2" 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× 1/2" NPT fittings and thread seal tape.

Instructions:
Preparation
The assembly of all calibrations shall meet the maximum flow requirement.
Please clean the port and fitting before installation, it will effectively avoid bringing dust to the air path.
Pay attention to the direction of air flow and the arrow pointing on the product body if correct, minding port and thread size if match.
Pressure Adjustment
Pull up the knob of the pressure gauge, rotate:
If you do clockwise rotation, pressure will rise steadily. Pressure will down when you rotate counterclockwise.
Stop turning after reaching the required index and lock down the knob, forget this step you may face a leakage problem.
Dial Reading
Make sure that the pressure gauge is tightly installed on the main body, and pay attention to whether the reading rises and falls smoothly while adjusting pressure.
Auto & Manual Drain
Auto: If a certain condensate filling level is reached inside the filter housing the condensate drain valve opens automatically draining the condensate through the condensate drain hose into the collection container( not included in delivery) until just a small residual quantity remains.
Manual: When water exceeds the level, please drain off the water to keep optimal dehumidification. Press up the bottom of the brass drain body, then it will start to drain.
Service Indicator
The service indicator on the coalescing filter signals when the filter element needs to be replaced.
When the indicator pops up, the element must be replaced.
