Coalescing Filters

Part No: E0613X1

Core Technical Specifications

Multi-layer gradient borosilicate glass fiber composite media, outer blue 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: 1.5°C ~ 80°C

Standard Replacement Cycle

4,000 working hours / 12 months under clean intake air; shorten to 2,000–3,000 hours for dusty spray booths and foundry environments. Mandatory replacement when differential pressure ΔP ≥ 0.06 MPa.

Differential Pressure Replacement Thresholds

Initial pressure drop of new element: ≤0.012 MPa

Mandatory replacement alarm threshold: ΔP ≥ 0.06 MPa

Sealing & Support Construction

End Cap: Reinforced black PA polymer bayonet lock head with uniform flow diversion ribs

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: Single-layer perforated 304 stainless steel mesh, lightweight anti-collapse reinforcement for stable medium-small airflow

Key Product Advantages

Front-stage pre-protection to greatly extend service life of downstream high-precision filters

Installed after the coarse prefilter, this X-grade element intercepts pipeline rust, massive condensed water and large 1μm oil mist. It drastically reduces oil contamination load on XA ultrafine coalescers and AC carbon filters, lowering overall factory spare parts cost and maintenance frequency.

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

Deep-pleated gradient glass fiber matrix stores abundant oil sludge, condensate and solid dust. The outer blue foam layer accelerates gravity liquid backflow, slowing pressure rise during continuous heavy-duty operation and reducing unplanned downtime for filter replacement.

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 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 medium-small volume compressed air flows through the filter cartridge from outside to inside:

Large water droplets and coarse solid impurities are trapped by outer blue hydrophobic foam and drain into 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 prevents separated liquid oil from being re-carried by high-speed 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 E0613XA ultrafine coalescing filter for secondary high-precision purification.

Application Industries

Small automotive component electrostatic spray booths, desktop laser marking & cutting equipment, laboratory & medical small gas supply, cosmetic micro-filling lines, small-scale pharmaceutical aseptic filling workshops, small food sterile packaging equipment, precision electronic component assembly workstations requiring medium-clean industrial compressed air.
