Key Product Advantages

All-in-one annual maintenance kit simplifies regular overhaul

Complete X+Y dual-stage filter elements plus matching gaskets are packed as one service kit. No separate spare parts ordering, eliminates leakage risks caused by mismatched or aged seals, fully restores original air purification performance of GKO851 filter housing.

Two-stage gradient filtration drastically extends service life of downstream activated carbon filter

X grade first removes bulk condensed water, rust and 1μm large oil mist; Y grade captures residual trace 0.01μm submicron oil aerosol. Dual-stage interception minimizes oil contamination load on terminal carbon elements, cutting overall spare parts consumption by over 40%.

Extra-large dirt & liquid holding capacity supports long-hour continuous heavy-duty production

Deep-pleated gradient microglass matrix stores massive oil sludge, condensate and solid dust. Color-coded outer drainage foam accelerates gravity liquid backflow, slowing pressure rise during full-load non-stop operation and reducing unplanned production downtime.

Heat-stabilized glass fiber media prevents fiber shedding and pipeline secondary pollution

High-temperature cured borosilicate media does not soften or pulverize under sustained high airflow temperature. No glass fiber debris enters air piping to block spray nozzles, laser optical lenses and proportional solenoid valves.

Low permanent differential pressure design reduces main compressor power consumption

Uniform gradient pore layout maintains ultra-low airflow resistance throughout full service life. Stable low backpressure lowers continuous running load of large screw compressors and cuts factory long-term electricity costs.

Working Principle

Dry pre-treated compressed air flows through filter cartridges from outside to inside:

Large water droplets and coarse solid impurities are trapped by outer hydrophobic foam and drain into filter bowl by gravity.

1μm oil-water aerosols coalesce into large liquid droplets while passing X grade gradient microglass media.

Remaining invisible 0.01μm submicron oil mist is fully captured by Y grade ultrafine media, merged into recoverable liquid oil.

Anti-re-entrainment foam prevents separated oil from being re-carried by high-speed large-volume airflow.

Collected condensate and oil are discharged automatically via electronic drain valve.

Ultra-clean compressed air flows downstream to activated carbon filter for final oil vapor removal.

Application Industries
