Coalescing Filters

Part No: E142KEA

Core Technical Specifications

Dual Filtration Grade:

Absolute Filtration Accuracy for Coalescing Layer: Solid particles & liquid oil/water aerosols ≥1 μm

Filter Media Composite Structure

Outer multi-layer deep-pleated borosilicate gradient glass fiber coalescing media with white hydrophobic PU anti-re-entrainment foam; inner encapsulated high-density food-grade granular activated carbon pre-filter layer, front glass fiber interception screen to block free liquid oil and prevent carbon premature poisoning.

3,000–4,000 operating hours / 12 months under clean low-oil-load environments; shorten to 1,500–2,200 hours for paint spray booths and high-humidity dusty workshops. Mandatory replacement when differential pressure ΔP ≥ 0.07 MPa or oily odor appears downstream.

Differential Pressure Replacement Thresholds

Initial pressure drop of brand-new element: ≤0.014 MPa

Mandatory alarm replacement threshold: ΔP ≥ 0.07 MPa

Sealing & Support Construction

End Cap: Reinforced black PA polymer push-fit bayonet lock cap with built-in flow diversion channels

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

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

Key Product Advantages

2-in-1 integrated dual-stage design saves installation space and reduces pipeline joints

Combines medium coalescing and pre-carbon adsorption into one single cartridge, replaces two separate elements E142KE + E142KA, cuts pipeline connection points, reduces air leakage risk and shortens maintenance time.

Pre-carbon layer reduces contamination burden of downstream ultrafine filter

After intercepting 1μm large oil mist via outer glass fiber media, the inner carbon core adsorbs most gaseous oil vapor in advance, greatly extending service life of E142KD ultrafine coalescer.

Large dust & oil holding capacity with stable low differential pressure

Proprietary deep-fold glass fiber matrix stores massive oil sludge and solid dust without rapid pressure rise, matching non-stop continuous production for small & medium air consumption workshops. Outer white hydrophobic foam rapidly drains liquid to filter bowl, minimizing oil re-entrainment risk.

Zero fiber & carbon powder shedding to avoid secondary pipeline contamination

High-temperature cured borosilicate glass fiber has stable structure without pulverization; fully sealed encapsulated carbon core prevents carbon powder from flowing into downstream pipelines, protecting spray guns, laser lenses and proportional solenoid valves.

Working Principle

Pre-dried medium-flow compressed air passes through the integrated cartridge from outside to inside:

Large water droplets and coarse solid impurities are trapped by outer white 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 outer gradient borosilicate glass fiber media.

Dry air enters the inner activated carbon layer; most gaseous oil vapor and odor molecules are adsorbed on carbon micropores.

Outer anti-re-entrainment foam barrier prevents separated liquid oil and water from being re-carried by high-speed medium-volume compressed airflow.

Medium-clean air with low residual oil vapor flows downstream to E142KD ultrafine coalescing filter for secondary high-precision polishing purification.

Application Industries

Small automotive component electrostatic spray booths, desktop laser marking & cutting equipment, small-scale laboratory pneumatic gas supply, mini food & beverage sterile packaging lines, compact workshop pneumatic pipelines with limited installation space requiring simplified filtration layout.
