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

Seal System: Integrated full-circle red 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 medium-flow operation

Key Product Advantages

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

F medium and H ultrafine glass fiber coalescing filters can only separate liquid oil mist, while this A-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 medium airflow, preventing blockage and carbon contamination of spray manifolds, laser optical lenses and miniature proportional solenoid valves.

Low-loss flow channel design reduces power consumption of medium 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 medium screw 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 H 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 medium-bore piping;

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

Application Industries

Medium automotive component electrostatic spray booths, standard laser marking & cutting production lines, medium-scale pharmaceutical aseptic filling workshops, cosmetic micro-filling lines, medical & dental small gas supply, medium food sterile packaging equipment, precision electronic component assembly workstations requiring strict ISO 8573-1 Class 0 oil-free compressed air.
