Key Product Advantages

Third-stage ultra-polishing element to protect downstream activated carbon filters and precision equipment

Installed after medium coalescing filter, this S-grade element removes invisible trace submicron oil mist and micro water droplets that cannot be captured by medium-grade filters. It drastically reduces oil contamination load on terminal AK activated carbon elements, extends carbon service life and cuts overall system maintenance and replacement costs.

Optimized multi-fold borosilicate fiber structure delivers larger filtration surface area and greater dirt/oil retention volume. It resists rapid pressure rise in high-humidity workshops where aftercooler performance is insufficient, minimizing unplanned production downtime for filter replacement.

Zero fiber shedding, no secondary pipeline contamination

Stable heat-treated borosilicate microfiber composite combined with full stainless steel cage eliminates fiber detachment under continuous airflow impact. No glass fiber debris will contaminate laser cutting machines, electrostatic spraying stations, medical and food-grade pneumatic equipment.

Low initial differential pressure to lower compressor energy consumption

Uniform gradient fiber distribution minimizes airflow resistance throughout the service life. Lower permanent pressure loss reduces continuous power draw of air compressors and long-term factory electricity operating costs.

Working Principle

Raw 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 oil & water submicron aerosols collide, merge and form large 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 carried back into high-speed compressed airflow;

Application Industries

Automotive electrostatic spray booths, small laser cutting equipment, pharmaceutical cleanroom production lines, food & beverage aseptic packaging, precision electronic manufacturing, laboratory analytical instruments, small standalone screw compressor stations, medical breathing air pretreatment, miniature pneumatic automation equipment.
