Continuous Operating Temperature: 1.5°C ~ 80°C

4,000 operating hours / 12 months under clean low-dust environments; shorten to 2,000–3,000 hours for paint spray booths, foundries and high-humidity dusty workshops. Mandatory replacement when differential pressure ΔP ≥ 0.06 MPa.

Initial pressure drop of brand-new element: ≤0.012 MPa

Mandatory alarm replacement threshold: ΔP ≥ 0.06 MPa

End Cap: Reinforced black PA plastic 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: Single-layer perforated 304 stainless steel mesh, lightweight anti-collapse reinforcement for stable medium airflow

Key Product Advantages

Mid-stage primary coalescing barrier to extend service life of downstream high-precision and carbon filters

Installed as the front coalescing stage before E150-HE ultrafine filter, GP grade intercepts massive condensed pipeline water, rust scale and large 1μm liquid oil mist. It drastically reduces liquid contamination load on downstream precision elements, extends overall consumable service cycle and cuts factory maintenance expenditure.

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 continuous production for medium air consumption workshops. Outer white 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 maintains stable structural integrity under long-term 80°C operating temperature without softening, pulverization or fiber shedding, preventing blockage of downstream precision equipment including spray guns, desktop laser optical lenses and miniature proportional solenoid valves.

Low permanent differential pressure energy-saving design to reduce air compressor power consumption

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

Working Principle

Pre-dried medium-flow compressed air passes through the filter cartridge from outside to inside:

Large water droplets and coarse solid impurities are trapped by outer white hydrophobic foam and drain down to the filter bowl by gravity.

1μm 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 and water from being re-carried by high-speed medium-volume compressed airflow.

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

Medium-clean air with residual liquid oil ≤0.1 mg/m³ flows downstream to E150-HE ultrafine coalescing filter for secondary high-precision purification.

Application Industries

Medium automotive component electrostatic spray booths, medium-format industrial laser cutting & welding equipment, small-medium pharmaceutical central aseptic filling stations, electronics factory workshop pneumatic pipelines, food & beverage medium sterile packaging lines requiring ISO 8573-1 Class 3 medium-clean industrial compressed air.
