Operating Limits

Max Working Pressure: 1.6 MPa

Recommended Continuous Operating Temperature: 1.5°C ~ 45°C

1,000 operating hours / 12 months (whichever comes first) under clean low-oil-load environments; shorten to 600–800 hours for dusty, high-humidity spray booth workshops. Mandatory replacement when oily odor appears downstream or differential pressure ΔP ≥ 0.07 MPa.

Differential Pressure Replacement Thresholds

Initial pressure drop of brand-new element: ≤0.015 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 full-circle 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

Final-stage ultra oil vapor elimination barrier to generate Class 0 completely oil-free compressed air

E142KE medium and E142KD ultrafine glass fiber coalescing filters only separate liquid oil mist; this KA carbon cartridge adsorbs invisible gaseous oil vapor that penetrates glass fiber media. It thoroughly removes oily odors and organic volatile contaminants to protect high-end finished products and precision process equipment.

Compact high-capacity encapsulated carbon core extends effective service life

High-filling-volume coconut shell activated carbon provides massive adsorption storage capacity within limited cylindrical space. The front glass fiber pre-layer intercepts residual liquid oil before contacting carbon media, avoiding premature carbon poisoning and prolonging service cycle.

Fully sealed anti-carbon-powder-shedding structure prevents secondary pipeline contamination

The carbon filling layer is fully wrapped and fixed by stainless steel mesh and stabilizing barrier. Zero carbon powder shedding under long-term continuous medium airflow, preventing blockage and carbon contamination of spray manifolds, laser optical lenses and miniature proportional solenoid valves.

Low-loss flow channel design reduces air compressor power consumption

Smooth graded internal flow structure minimizes airflow resistance under full rated flow. Low dry-state pressure loss reduces continuous running load of screw air compressors and cuts long-term workshop electricity operating costs.

Working Principle

Dry pre-purified medium-volume compressed air flows through the filter cartridge from outside to inside:

Front integrated glass fiber interception layer traps residual tiny liquid oil droplets and fine solid particles carried over from upstream E142KD ultrafine filter;

Clean dry gas penetrates the high-density activated carbon core; gaseous oil vapor, hydrocarbon and odor molecules are permanently adsorbed onto carbon micropores;

Outer stainless steel protective mesh prevents media abrasion and carbon powder from flowing into downstream medium-bore piping;

Oil-vapor-free, odorless ultra-clean compressed air exits from the inner stainless steel support tube and supplies terminal precision production equipment.

Application Industries

Small & medium automotive component electrostatic spray booths, desktop laser marking & cutting equipment, small-scale pharmaceutical aseptic filling stations, cosmetic micro-filling production lines, laboratory & medical high-purity gas supply, food & beverage small sterile packaging equipment, precision electronic component assembly cleanrooms requiring strict ISO 8573-1 Class 0 zero-oil compressed air.
