Coalescing Filters

Part No: EA430U

Core Technical Specifications

Multi-layer deep-pleated gradient borosilicate glass fiber composite media, outer green hydrophobic & oleophobic PU drainage foam. Extra deep pleat design expands filtration area for large dust/oil holding capacity, integrated anti-re-entrainment barrier prevents separated liquid oil from being re-carried by high-speed ultra-large airflow.

Max Working Pressure: 1.6 MPa

6,000 working hours / 12 months (whichever comes first) under clean intake air; shorten to 3,000 hours for dusty spray booth, foundry and high-humidity environments. Mandatory replacement when differential pressure ΔP ≥ 0.06 MPa.

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

Mandatory replacement alarm threshold: ΔP ≥ 0.06 MPa

End Cap: CNC machined solid 304 stainless steel top & bottom end caps with central locating boss for quick positioning

Seal System: One-piece full-circle NBR nitrile rubber O-ring, zero air bypass, 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

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

Installed after water separator and P-grade dust prefilter, U grade intercepts pipeline bulk condensed water, rust particles and large 1μm liquid oil mist. It drastically reduces liquid contamination load on EA430H ultrafine and EA430C carbon filters, cutting overall factory spare parts consumption and maintenance frequency.

Ultra-large dirt & 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, perfectly matching non-stop heavy-duty continuous production for ultra-large air consumption workshops. Outer green 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 oil-gas mixing conditions, 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 design reduces large compressor power consumption

Uniform gradient pore layout maintains minimal airflow resistance throughout 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 filter cartridge from outside to inside:

Large water droplets and coarse solid impurities are trapped by outer green 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 ultra-large-volume compressed airflow.

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

Medium-clean air with residual liquid oil ≤0.1 mg/m³ flows downstream to EA430H ultrafine coalescing filter for secondary high-precision purification.

Application Industries

Full vehicle automotive electrostatic spray production lines, heavy industry large-format laser cutting workshops, large-scale pharmaceutical central aseptic filling air supply, electronics factory super large cleanroom main gas source, food & beverage large sterile packaging plants, multi-station heavy automation production lines with ultra-high air demand requiring medium-clean industrial compressed air.
