Core Technical Specifications

Absolute Filtration Accuracy: Solid particles & liquid oil/water aerosols ≥0.01 μm

Multi-layer deep-bed imported HV borosilicate gradient glass fiber composite media, outer thick red hydrophobic & oleophobic PU drainage foam. Integrated liquid diversion anti-re-entrainment barrier prevents separated liquid oil from being re-carried by high-speed large airflow.

Operating Limits

Max Working Pressure: 1.6 MPa

Continuous Operating Temperature: 1°C ~ 80°C

Standard Replacement Cycle

4,000 operating hours / 12 months (whichever comes first) under clean low-dust environments; shorten to 2,000–3,000 hours for paint booths, foundries and high-humidity workshops. Mandatory replacement when differential pressure ΔP ≥ 0.07 MPa.

Differential Pressure Replacement Thresholds

Initial pressure drop of brand-new element: ≤0.013 MPa

Mandatory alarm replacement threshold: ΔP ≥ 0.07 MPa

Sealing & Support Construction

End Cap: Reinforced black PA polymer integrated bayonet lock cap with built-in flow diversion channels

Seal System: One-piece molded NBR nitrile rubber O-ring, zero bypass leakage, resistant to compressor oil aging and acidic condensate corrosion

Inner & Outer Support Cage: Double-layer perforated 304 stainless steel mesh, heavy-duty anti-collapse reinforcement for stable ultra-large airflow

Key Product Advantages

Core high-precision polishing stage to drastically extend downstream carbon filter service life

Installed after GP medium coalescer, CHE-E grade captures invisible trace submicron oil mist and micro water droplets that 1μm medium filters cannot separate. It greatly reduces liquid contamination load on terminal AC activated carbon elements, extends carbon service cycle and cuts overall factory spare parts expenditure.

Ultra-large dust & oil holding capacity with stable low differential pressure

Proprietary deep-fold glass fiber matrix stores massive oil sludge, condensate and solid dust without rapid pressure rise, matching non-stop heavy-duty continuous production for ultra-large air consumption workshops. Outer red hydrophobic foam rapidly drains liquid to filter bowl, minimizing oil re-entrainment risk.

Heat-stabilized glass fiber media eliminates fiber shedding and secondary pipeline contamination

High-temperature cured borosilicate glass fiber remains stable under long-term 80°C operating temperature, no softening or pulverization. Zero glass fiber debris enters air piping to block spray guns, industrial laser lenses and proportional solenoid valves.

Low permanent differential pressure energy-saving design reduces large compressor power consumption

Uniform gradient pleat layout delivers minimal airflow resistance over the full service cycle. Stable low backpressure reduces continuous motor load of large screw air compressors and slashes long-term workshop electricity operating costs.

Working Principle

Pre-dried ultra-large-volume compressed air flows through the filter cartridge from outside to inside:

Residual tiny water droplets and fine solid impurities are trapped by outer red hydrophobic foam and drain down to the filter bowl by gravity.

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

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

Collected oil and condensate are automatically discharged via electronic zero-loss drain valve.

Ultra-clean air with residual liquid oil ≤0.008 mg/m³ flows downstream to AC activated carbon filter for secondary oil vapor removal.
