Key Product Advantages

Installed after KE fine coalescing filter, this FE-grade element intercepts invisible trace submicron oil mist and micro water droplets that medium-grade filters cannot separate. It drastically reduces oil contamination load on terminal KA activated carbon cartridges, extends carbon service life and cuts overall system maintenance & spare parts expenditure.

Extra-large oil & liquid holding capacity for heavy-load central compressor stations

Thick deep-pleated gradient micro glass fiber matrix provides massive dirt/liquid retention volume. It resists rapid pressure rise in high-humidity factories with failed or underperforming aftercoolers/refrigerated dryers, minimizing unplanned production downtime for filter replacement.

Zero fiber shedding integrated design, eliminates secondary pipeline contamination

Heat-stabilized integrated borosilicate microfiber composite together with full stainless steel cladding cage prevents fiber detachment under long-term high-flow humid airflow impact. No glass fiber debris will contaminate heavy laser cutting machines, automotive spray booths, pharmaceutical cleanroom and food-grade pneumatic devices.

Low permanent differential pressure to reduce central compressor station energy consumption

Uniform gradient pore distribution minimizes airflow resistance throughout the full service cycle. Stable low backpressure cuts continuous power draw of large screw air compressors and reduces long-term factory electricity operating costs.

Working Principle

Pre-cleaned compressed air flows through the filter cartridge from outside to inside:

Residual large condensed water droplets and fine solid particles are blocked by the outer red hydrophobic drainage foam layer;

Micro submicron oil & water aerosols collide, merge and form large separable liquid droplets while passing through multi-layer gradient borosilicate micro glass fiber media;

The outer anti-re-entrainment foam prevents coalesced liquid droplets from being re-carried into high-speed large-volume compressed airflow;

Ultra-dry compressed air with extremely low residual liquid oil content flows downstream to the activated carbon filter for final oil vapor adsorption processing.

Application Industries

Large automotive electrostatic spray workshops, multi-line heavy laser cutting equipment, pharmaceutical cleanroom aseptic filling production lines, mass food & beverage aseptic packaging, PCB & semiconductor precision component manufacturing, laboratory large analytical instruments, factory centralized medical breathing air pretreatment, heavy industry large screw compressor stations, full-automatic ultra-large pneumatic automation production lines, front protective filter for large adsorption dryers.
