Coalescing Filters

Part No: EA430H

Core Technical Specifications

6-layer deep-bed gradient borosilicate glass fiber composite media, outer blue hydrophobic & oleophobic PU drainage foam. Deep pleated structure maximizes dust/oil holding capacity, integrated anti-re-entrainment barrier prevents separated liquid oil from being re-carried by high-speed large airflow.

Continuous Operating Temperature: -10°C ~ 80°C

6,000 working hours / 12 months under clean intake air; shorten to 3,000 hours for dusty spray booth, foundry and high-humidity environments. Mandatory replacement when differential pressure ΔP ≥ 0.07 MPa.

Differential Pressure Replacement Thresholds

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

Mandatory replacement alarm threshold: ΔP ≥ 0.07 MPa

Sealing & Support Construction

End Cap: Solid CNC machined 304 stainless steel upper & lower end caps, central locating boss for quick positioning

Seal System: Built-in full-circle NBR nitrile rubber O-ring, zero air bypass, resistant to aging caused by high-temperature compressor oil and acidic condensate

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

Key Product Advantages

Fourth-stage high-precision polishing protection to drastically extend service life of downstream carbon filters

Installed after EA430U medium coalescer, this H-grade element captures invisible trace submicron oil mist and micro water droplets that medium filters cannot separate. It greatly reduces liquid contamination load on terminal EA430C activated carbon elements, extends carbon service cycle and cuts overall factory spare parts expenditure.

Ultra-large dirt & oil holding capacity with stable low differential pressure during long full-load production

Proprietary 6-layer deep-bed glass fiber matrix stores massive oil sludge, condensate and solid dust without rapid pressure rise, perfectly matching non-stop heavy-duty continuous production for large air consumption workshops. The outer thick blue foam layer accelerates gravity liquid backflow to reduce liquid residue inside filter bowl.

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 clog 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 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 blue hydrophobic foam and drain into 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 EA430C activated carbon filter for secondary oil vapor removal.
