Key Product Advantages

Third-stage high-precision polishing protection greatly extends service life of downstream ND carbon filter

Installed after B medium coalescing filter, this upgraded C/F-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 cuts overall workshop spare parts expenditure.

Compact large dirt & liquid holding capacity ensures stable low differential pressure

Deep-pleated gradient microglass matrix stores abundant oil, condensate and solid dust contaminants within small dimensions. Outer red drainage foam accelerates liquid gravity backflow, slowing pressure rise in small & medium production air systems and reducing unplanned downtime caused by frequent filter replacements.

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

Heat-cured borosilicate microglass composite paired with stainless steel support mesh stops glass fiber powder from shedding into small-bore air piping, protecting micro spray nozzles, tiny laser optical lenses and miniature proportional solenoid valves from severe clogging failures.

Energy-saving low differential pressure design reduces power consumption of small air compressors

Uniform wide-gradient pore layout maintains ultra-low airflow resistance under full rated flow throughout the entire service life. Stable low backpressure lowers continuous running load of mini screw compressors and portable air pumps, significantly cutting long-term workshop electricity operating costs.

Working Principle

Pre-filtered 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 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 compressed airflow.

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

Ultra-clean air with residual liquid oil ≤0.01 mg/m³ flows downstream to ND activated carbon filter for final oil vapor purification.
