Coalescing Filters

Part No: CE0600NCNT

Core Technical Specifications

Multi-layer deep-pleated imported borosilicate gradient glass fiber composite media, integrated hydrophobic & oleophobic PU drainage foam on outer layer. Built-in liquid diversion anti-re-entrainment barrier traps separated liquid oil and water to avoid re-entrainment into pipelines by high-speed airflow.

Max Working Pressure: 1.6 MPa

Continuous Operating Temperature: 1°C ~ 80°C

4,000 operating hours or 12 months (whichever comes first) under clean workshop environments; shorten to 2,000–3,000 hours for paint 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 new element: ≤0.012 MPa

Mandatory alarm replacement threshold: ΔP ≥ 0.06 MPa

Sealing & Support Construction

End Cap: Reinforced black PA plastic integrated claw lock head with built-in flow diversion channels

Seal System: One-piece molded NBR nitrile rubber O-ring, zero bypass leakage, resistant to aging caused by compressor oil and acidic condensate corrosion

Inner & Outer Support Cage: Single-layer perforated 304 stainless steel mesh, lightweight anti-collapse reinforcement for stable airflow under full flow rate

Key Product Advantages

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

Installed after BNT prefilter and before NDNT ultrafine filter, it intercepts massive condensed pipeline water, rust particles and large 1μm liquid oil mist. It significantly reduces liquid contamination load on downstream high-precision filter elements, extends overall consumable service cycle by over 50% and cuts factory maintenance costs.

Large dust & oil holding capacity with stable low differential pressure throughout service life

Proprietary deep-pleated glass fiber matrix holds large volume of oil sludge and dust without rapid pressure rise, suitable for 24-hour non-stop heavy-duty production lines. Outer hydrophobic foam quickly drains liquid to the filter bowl drain port and greatly reduces oil re-entrainment risk.

High-temperature stable glass fiber media with zero fiber shedding to avoid pipeline contamination

High-temperature cured borosilicate glass fiber maintains stable structure under long-term 80°C operating temperature without softening, pulverization or fiber shedding, preventing blockage of downstream precision equipment such as spray guns, laser lenses and proportional solenoid valves.

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

Uniform gradient pleat layout delivers minimal airflow resistance over the full service cycle. Stable low backpressure reduces compressor loading load and lowers long-term workshop electricity consumption.

Working Principle

Dry medium-flow compressed air passes through the filter cartridge from outside to inside:

Large water droplets and coarse solid impurities are trapped by outer hydrophobic foam and drain down to 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 barrier prevents separated liquid oil and water 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 CE0600NDNT ultrafine coalescing filter for secondary high-precision purification.
