Coalescing Filters

Part No: EA350H

Core Technical Specifications

Multi-layer gradient imported HV borosilicate glass fiber composite media, outer yellow hydrophobic & oleophobic PU drainage foam. Extra deep pleated design maximizes dirt holding capacity with built-in anti-re-entrainment barrier to prevent separated liquid oil from being re-carried by high-speed airflow.

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

6,000–8,000 working hours / 12 months under clean intake air; shorten to 3,000 hours for dusty spray booth and foundry environments. Mandatory replacement when differential pressure ΔP ≥ 0.07 MPa.

Differential Pressure Replacement Thresholds

Initial pressure drop of new element: ≤0.013 MPa

Mandatory replacement alarm threshold: ΔP ≥ 0.07 MPa

Seal System: Integrated 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 medium-large flow operation

Key Product Advantages

Fourth-stage high-precision polishing protection to greatly extend service life of downstream carbon filter

Installed after X-grade medium coalescer, this H-grade element captures invisible trace submicron oil mist and micro water droplets that medium filters cannot separate. It drastically reduces liquid contamination load on terminal EA350C activated carbon elements, extends carbon service cycle and lowers overall factory spare parts expenditure.

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

Deep-pleated gradient glass fiber matrix stores massive oil sludge, condensate and solid dust without rapid pressure rise, suitable for non-stop heavy-duty continuous production. The outer yellow foam layer accelerates gravity liquid backflow to reduce liquid residue inside the filter bowl.

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

High-temperature cured borosilicate glass fiber will not soften or pulverize under 80°C oil-gas mixing conditions. No glass fiber debris enters air piping to clog spray guns, laser optical lenses and proportional solenoid valves.

Low permanent differential pressure design cuts compressor power consumption

Uniform gradient pore layout maintains minimal airflow resistance throughout the full service cycle. Stable low backpressure reduces continuous load on screw air compressors and lowers long-term workshop electricity costs.

Working Principle

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

Residual tiny water droplets and fine solid impurities are trapped by outer yellow 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 prevents separated liquid oil from being re-carried by high-speed medium-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 EA350C activated carbon filter for secondary oil vapor removal.

Application Industries

Automotive component electrostatic spray booths, medium-format laser marking & cutting production lines, medium-scale pharmaceutical aseptic filling workshops, electronics factory central clean air supply, food & beverage medium sterile packaging lines, multi-station automation production lines requiring strict ISO 8573-1 Class 1 ultra-clean compressed air.
