End Caps: Reinforced black PA polymer external bayonet quick-lock connector with uniform flow diversion ribs

Seal System: Integrated full-circle red NBR nitrile rubber O-ring, zero air bypass, resistant to aging caused by high-temperature compressor oil and acidic condensate

Inner & Outer Support Cage: Single-layer perforated 304 stainless steel mesh, lightweight anti-collapse reinforcement for stable long-term medium airflow

Key Product Advantages

Second-stage front polishing protection greatly extends service life of downstream H and A precision filters

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

Large dirt & liquid holding capacity ensures stable low differential pressure during long heavy-duty continuous production

Deep-pleated gradient microglass matrix stores abundant oil, condensate and solid dust contaminants within compact dimensions. Outer blue drainage foam accelerates liquid gravity backflow, slowing pressure rise in medium-flow production air systems and reducing unplanned downtime caused by frequent filter replacements.

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

Heat-cured borosilicate microglass composite paired with stainless steel support mesh stops glass fiber powder from shedding into medium-bore air piping, protecting medium spray manifolds, standard laser optical lenses and miniature proportional solenoid valves from severe clogging failures.

Energy-saving low differential pressure design reduces power consumption of medium screw air compressors

Uniform wide-gradient pore layout maintains ultra-low airflow resistance under full rated flow throughout the entire service life. Stable low backpressure reduces continuous running load of medium screw compressors and significantly cuts long-term workshop electricity operating costs.

Working Principle

Pre-dried medium-volume compressed air flows through the filter cartridge from outside to inside:

Large water droplets and solid impurities are intercepted by outer blue hydrophobic foam and drain into the 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 medium-volume compressed airflow.

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

Medium-clean air with residual liquid oil ≤0.1 mg/m³ flows downstream to H ultrafine coalescing filter for secondary high-precision purification.

Application Industries

Medium automotive component assembly workshops, general metal cutting & welding production lines, small plastic injection molding factories, standard laser marking equipment supporting air supply, non-critical pneumatic tools, packaging machinery, medium workshop general air pipelines requiring medium-clean industrial compressed air.
