Sealing & Support Construction

End Caps: Reinforced black PA polymer internal threaded positioning head with uniform large-area flow diversion ribs

Seal System: Integral full-circle NBR nitrile rubber flange gasket, zero air bypass, resistant to aging caused by high-temperature compressor oil and acidic condensate

Inner & Outer Support Cage: Double-layer thick perforated 304 stainless steel mesh, heavy-duty structural reinforcement to avoid media bulging or collapse under full rated high airflow

Key Product Advantages

Second-stage large-flow medium polishing protection to extend service life of downstream H & A precision filters

Installed after primary coarse prefilter, this X-grade element intercepts massive pipeline rust, bulk condensed water and 1μm large oil mist under factory central heavy airflow. It drastically reduces liquid contamination load on ultrafine and carbon filter elements, extends their service cycle and lowers overall factory spare parts expenditure.

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

Extra deep-pleated gradient microglass matrix stores massive volumes of oil, condensate and solid dust contaminants. Outer blue drainage foam accelerates liquid gravity backflow, slowing pressure rise under full-load long-hour operation and reducing costly unplanned full-line downtime caused by frequent filter replacements.

High-temperature stabilized media eliminates fiber shedding and secondary pipeline contamination

Heat-cured borosilicate microglass composite paired with double heavy stainless steel support mesh stops glass fiber powder from shedding into large-diameter central air pipelines, protecting heavy spray booth manifolds, large-format laser cutting lenses and main process proportional solenoid valves from severe clogging failures.

Energy-saving low differential pressure design cuts power consumption of large screw/centrifugal compressors

Uniform wide-gradient pore layout maintains ultra-low airflow resistance under maximum rated flow throughout the entire service life. Stable low backpressure reduces continuous running load of large industrial air compressors, significantly cutting long-term factory electricity operating costs.

Working Principle

High-volume compressed air flows through the filter cartridge from outside to inside:

Large water droplets and solid impurities are trapped by outer blue hydrophobic foam and drain into the large filter bowl via gravity.

1μm oil-water micro-aerosols collide and coalesce into large separable liquid droplets while passing through multi-layer gradient borosilicate microglass media.

Outer anti-re-entrainment foam prevents separated liquid oil from being re-carried by high-speed large-volume compressed airflow.

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

Medium-clean dry compressed air flows downstream to H ultrafine coalescing filter for secondary high-precision purification.
