Key Product Advantages

Third-stage ultra-fine polishing barrier to protect downstream C-grade activated carbon filter

Installed after A medium coalescing filter, this HE element captures invisible trace 0.01μm submicron oil mist and micro water droplets that medium filters cannot separate. It drastically reduces liquid oil load on terminal carbon cartridges, extends carbon service life and lowers overall spare parts expenditure.

Medium-size high dirt & liquid holding capacity for stable continuous operation

Thick deep-pleated imported microglass matrix stores large volumes of oil and condensate. Outer white drainage foam accelerates liquid gravity backflow, slowing pressure rise in medium factory air loops and reducing unplanned production downtime from frequent filter replacement.

High-temperature stabilized media, zero fiber shedding to avoid pipeline secondary contamination

Heat-cured HV borosilicate microglass composite paired with double stainless steel mesh prevents glass fiber powder shedding into medium-diameter air piping, protecting medium-format spray booth equipment, standard laser cutting lenses and process proportional solenoid valves from severe clogging failures.

Low permanent differential pressure design to cut compressor power consumption

Uniform gradient pore layout maintains ultra-low airflow resistance under rated full flow throughout the whole service cycle. Stable low backpressure reduces continuous running load of medium screw compressors, significantly cutting factory daily electricity operating costs.

Working Principle

Pre-filtered compressed air flows through the cartridge from outside to inside:

Residual small water droplets and fine solid impurities are trapped by outer white hydrophobic foam and drain to filter bowl by 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 medium-volume compressed airflow.

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

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

Application Industries

Medium automotive electrostatic spray booths, standard laser marking & cutting production lines, pharmaceutical medium-scale aseptic filling workshops, electronics factory central cleanroom air supply, food & beverage medium sterile packaging plants, multi-station medium automation production lines requiring ISO 8573-1 Class 1 ultra-pure compressed air.
