Key Product Advantages

lt drastically reduces trace liquid oil contamination load on terminal AU activated carbon cartridges, extends carbon service life and cuts overall system maintenance & spare parts expenditure. Silicon-free formulation is optional for automotive topcoat painting lines to eliminate paint pinhole and fogging defects.

Ultra-large liquid holding capacity for high-humidity heavy industrial environments

Thick deep-pleated epoxy-impregnated micro glass fiber matrix stores massive volumes of condensed oil and condensate, resisting rapid saturation in large factories with underperforming aftercoolers or refrigerated dryers. Widely installed upstream of large adsorption dryers to protect molecular sieve media from permanent oil fouling.

Optimized low airflow resistance to cut central compressor station energy consumption

Uniform deep-fold micro glass fiber maximizes effective filtration area, maintaining ultra-stable low pressure drop under 24/7 continuous full-load large-volume operation, minimizing extra power draw of central air compressor units and long-term electricity costs.

Hydrolysis & abrasion resistant media with zero fiber shedding

Epoxy-saturated oleophobic borosilicate micro glass fiber combined with full stainless steel rigid support cage prevents fiber detachment under long-term high-flow humid compressed air impact, avoiding secondary pipeline contamination to downstream large precision processing equipment.

Standard bayonet quick-swap design without full housing disassembly

Uniform industrial bayonet base perfectly matches Parker Finite H35-280 series large flow filter housings; a single operator can complete cartridge replacement within 3 minutes without removing the entire filter tank.

Working Principle

Residual bulk condensed water and fine solid particles are blocked by outer hydrophobic anti-re-entrainment media layer;

Trace micro oil & water aerosols collide and coalesce into large liquid droplets through multi-layer gradient epoxy borosilicate micro glass fiber media;

Outer retention media prevents coalesced liquid droplets from being re-entrained into high-speed large-volume airflow;

Application Industries

Large automotive electrostatic spray workshops, multi-line heavy laser cutting equipment, large pharmaceutical sterile filling production lines, mass food aseptic packaging plants, PCB & semiconductor chip manufacturing facilities, laboratory large precision analytical instruments, factory centralized medical breathing air pretreatment, heavy industry central air compressor stations, large solvent mass spraying production lines, full-automatic ultra-precision large pneumatic automation production lines, front protection filter for large adsorption dryers.
