Key Product Advantages

Third-stage high-precision polishing protection drastically extends service life of downstream V carbon filter

Installed after X medium coalescing filter, this upgraded Y-grade element captures invisible trace submicron oil mist and micro water droplets that medium filters cannot separate. It drastically reduces liquid contamination load on terminal activated carbon elements, extends carbon service cycle and lowers overall factory spare parts expenditure.

Ultra-large dirt & liquid holding capacity ensures stable low differential pressure during long heavy-duty continuous production

Extra deep-pleated gradient microglass matrix stores massive volumes of oil, condensate and solid dust contaminants. Outer red drainage foam accelerates liquid gravity backflow, slowing pressure rise under full-load long-hour operation and reducing costly unplanned full-line downtime caused by frequent filter replacements.

High-temperature stabilized media eliminates fiber shedding and secondary pipeline contamination

Heat-cured borosilicate microglass composite paired with double heavy stainless steel support mesh stops glass fiber powder from shedding into large-diameter central air pipelines, protecting heavy spray booth manifolds, large-format laser cutting lenses and main process proportional solenoid valves from severe clogging failures.

Energy-saving low differential pressure design cuts power consumption of large screw/centrifugal compressors

Uniform wide-gradient pore layout maintains ultra-low airflow resistance under maximum rated flow throughout the entire service life. Stable low backpressure reduces continuous running load of large industrial air compressors, significantly cutting long-term factory electricity operating costs.

Working Principle

High-volume compressed air flows through the filter cartridge from outside to inside:

Residual tiny water droplets and fine solid impurities are intercepted by outer red hydrophobic foam and drain into the large filter bowl via gravity.

0.01μm ultra-fine oil-water micro-aerosols collide and coalesce into large separable liquid droplets while passing through multi-layer gradient borosilicate microglass media.

Outer anti-re-entrainment foam prevents separated liquid oil from being re-carried by high-speed large-volume compressed airflow.

Collected oil and condensate are automatically discharged via large electronic float drain valve.

Ultra-clean air with residual liquid oil ≤0.008 mg/m³ flows downstream to V activated carbon filter for final oil vapor purification.
