Key Product Advantages

Core third-stage ultra-clean polishing filter for heavy-duty large-flow central compressed air systems

It drastically reduces trace liquid oil contamination load on downstream activated carbon adsorption equipment, extends carbon service life and cuts overall system maintenance & spare parts expenditure. Silicone-free media eliminates paint pinhole and fogging defects for automotive topcoat spraying workshops.

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

Thick deep-pleated gradient 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 large screw air compressor units and long-term electricity costs.

Hydrolysis & abrasion resistant media with zero fiber shedding

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.

Kaeser standard bayonet quick-swap design without full housing disassembly

Central positioning metal mandrel perfectly matches E185 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 white hydrophobic foam layer;

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

Outer anti-re-entrainment foam 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 cleanroom 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.
