Key Product Advantages

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

Installed after DD medium coalescing filter, this PD-grade cartridge intercepts invisible trace submicron oil mist and micro water droplets that medium-grade filters cannot separate. It drastically reduces oil contamination load on terminal QD170 activated carbon cartridges, extends carbon service life and cuts overall factory spare parts & maintenance costs.

Extra-large oil & liquid holding capacity for stable long-cycle continuous operation

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

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

Heat-cured solidified microfiber composite combined with double-layer stainless steel support mesh prevents fiber powder detachment under long-term medium-flow airflow impact. No glass fiber debris will block spray guns, laser optical lenses and miniature pneumatic control valves.

Ultra-low permanent differential pressure to reduce air compressor energy consumption

Uniform gradient pore distribution minimizes airflow resistance throughout the full service lifespan. Stable low backpressure reduces continuous power draw of medium screw air compressors and lowers long-term factory electricity expenses.

Working Principle

Residual large condensed water droplets and fine solid particles are trapped and drained by the outer red hydrophobic foam layer, flowing down to filter bowl via gravity;

Micro submicron oil & water aerosols collide, coalesce 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 compressed airflow;

Separated oil and condensate collect at filter bowl and discharge automatically via Atlas Copco EWD auto drain valve;

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

Application Industries

Precision electronic component assembly workshops, medium electrostatic spray booths, medium laser marking & cutting equipment, pharmaceutical small-batch filling gas supply, laboratory analytical instrument air source, cosmetic filling production lines, food aseptic packaging equipment, automated production lines requiring strict high air purity control.
