Coalescing Filters

Part No: E142KE

Core Technical Specifications

Multi-layer deep-pleated imported borosilicate gradient glass fiber composite media, outer integrated hydrophobic & oleophobic PU drainage foam. Built-in liquid diversion anti-re-entrainment barrier prevents separated liquid oil from being re-carried by continuous airflow.

Max Working Pressure: 1.6 MPa

Continuous Operating Temperature: 1.5°C ~ 80°C

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

Differential Pressure Replacement Thresholds

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

Mandatory alarm replacement threshold: ΔP ≥ 0.06 MPa

Sealing & Support Construction

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

Seal System: One-piece full-circle 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

Front-stage primary coalescing protection to extend service life of downstream precision filters

Installed after E142KB particulate prefilter, KE grade intercepts massive condensed pipeline water, rust particles and large 1μm liquid oil mist. It drastically reduces liquid contamination load on E142KD ultrafine and terminal E142KA activated carbon elements, cuts overall factory spare parts consumption and maintenance frequency.

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

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

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

Working Principle

Pre-dried medium-volume compressed air flows through filter cartridge from outside to inside:

Large water droplets and coarse solid impurities are trapped by outer white hydrophobic foam, drain down to 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 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 E142KD ultrafine coalescing filter for secondary high-precision purification.

Application Industries

Small automotive component electrostatic spray booths, desktop laser marking & cutting equipment, small-scale pharmaceutical aseptic filling stations, electronics factory small pneumatic pipelines, food & beverage mini sterile packaging lines, general machinery pneumatic tools requiring ISO 8573-1 Class 3 medium-clean industrial compressed air.
