Sealing & Support Construction

End Caps: Reinforced black PA triple-lug locking head with flow diversion ribs to reduce airflow turbulence

Key Product Advantages

Third-stage ultra-fine polishing barrier to protect downstream 85565562 activated carbon filters and high-sensitivity precision equipment

Installed after GP medium filter, this HE-grade cartridge intercepts invisible trace submicron oil mist and micro water droplets that medium filters cannot separate. It drastically reduces oil contamination load on terminal carbon cartridges, extends carbon service life and cuts spare parts cost.

Large dirt & liquid holding capacity for stable long-cycle operation

Thick deep-pleated microglass matrix provides high oil/water storage capacity; outer drainage foam accelerates liquid separation and gravity discharge, slowing pressure rise in humid workshop environments and reducing unplanned downtime from frequent filter replacement.

Heat-stabilized media, zero fiber shedding to avoid pipeline secondary pollution

Heat-cured borosilicate microglass composite combined with stainless steel support mesh prevents glass fiber powder shedding into pipelines, protecting precision micro spray nozzles, tiny laser optical lenses and miniature solenoid valves from blockage failure.

Low permanent differential pressure to reduce air compressor energy consumption

Uniform gradient pore structure minimizes airflow resistance throughout service life; stable low backpressure lowers continuous power consumption of medium screw compressors and reduces long-term electricity cost.

Working Principle

Medium-clean compressed air flows from outside to inside the cartridge:

Residual large water droplets and fine solid impurities are trapped by outer red hydrophobic foam, draining down to filter bowl via gravity;

0.01μm ultra-fine oil-water micro-aerosols collide and coalesce into large separable liquid droplets while passing through multi-layer gradient microglass media;

Outer anti-re-entrainment foam prevents separated liquid droplets from being re-carried by high-speed airflow;

Collected oil and condensate are automatically discharged by electronic float drain valve;

Ultra-dry air with residual oil ≤0.01mg/m³ flows downstream to activated carbon filter for final vapor removal.

Application Industries

Precision electronic component assembly, automotive electrostatic spray booths, laser marking/cutting equipment, pharmaceutical filling gas supply, laboratory analytical instruments, cosmetic micro-filling lines, medical dental gas supply, food aseptic packaging, automated test benches requiring Class 1 ultra-pure compressed air.
