Key Product Advantages

Third-stage ultra-fine polishing barrier to protect downstream 0125ES activated carbon filters and high-sensitivity miniature precision production equipment

Installed after 0125EM medium coalescing filter, this EH-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 activated carbon cartridges, extends carbon service life and cuts factory spare parts & maintenance expenses.

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

Thick deep-pleated microglass matrix provides massive liquid retention volume. It resists rapid pressure rise in humid production workshops with underperforming aftercoolers or refrigerated dryers, minimizing unplanned equipment downtime from frequent filter swaps.

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

Heat-cured solidified microglass composite paired with stainless steel support mesh prevents fiber powder detachment under long-term small-volume airflow impact. No glass fiber debris will block micro spray nozzles, tiny laser optical lenses and miniature solenoid valves.

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

Uniform gradient pore layout minimizes airflow resistance throughout the full service lifespan. Stable low backpressure cuts continuous power draw of mini screw air compressors and lowers long-term factory electricity costs.

Working Principle

Medium-clean compressed air flows through the filter cartridge from outside to inside:

Residual large condensed water droplets and fine solid particles are trapped and drained by the outer 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 microglass media;

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

Separated oil and condensate collect at filter bowl and discharge automatically via mini electronic float auto drain valve;

Ultra-dry compressed air with extremely low residual liquid oil content flows downstream into 0125ES activated carbon filter for final oil vapor adsorption treatment.
