Coalescing Filters

Part No: E811AC

Core Technical Specifications

Pre-Filtration Interception Capacity: Captures residual ≥0.01μm fine liquid oil mist and solid particles

Outer white hydrophobic PU anti-re-entrainment drainage foam

Front multi-layer borosilicate glass fiber pre-screen to block residual liquid oil droplets

Core high-density coconut shell granular activated carbon matrix, fully sealed anti-carbon-powder-shedding encapsulated construction

1,000 working hours / 12 months under clean low-oil-load industrial environments; shorten to 600–800 hours for dusty, high-humidity spray booth environments. 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 replacement alarm threshold: ΔP ≥ 0.07 MPa

Sealing & Support Construction

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

Seal System: Integrated full-circle NBR nitrile rubber O-ring, zero air bypass, resistant to high-temperature compressor oil and acidic condensate aging

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

Key Product Advantages

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

AO medium and AA ultrafine glass fiber coalescing filters can only separate liquid oil mist, while this AC-grade carbon cartridge adsorbs invisible gaseous oil vapor penetrating coalescing 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 delivers stable extended service life

High-filling-volume coconut shell activated carbon provides massive adsorption storage capacity within limited space. The front glass fiber pre-layer intercepts residual liquid oil before contacting carbon media, avoiding premature carbon poisoning and extending effective 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 white drainage foam. Zero carbon powder shedding under long-term continuous small airflow, preventing blockage and carbon contamination of small spray manifolds, laser optical lenses and miniature proportional solenoid valves.

Low-loss flow channel design reduces power consumption of small screw air compressors

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

Working Principle

Dry pre-purified small-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 E811AA 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 foam abrasion and carbon powder from flowing into downstream small-bore piping;

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

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 strict ISO 8573-1 Class 0 oil-free compressed air.
