Key Product Advantages

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

DD/PD glass fiber filters only separate liquid oil mist; this A-grade carbon element adsorbs invisible gaseous oil vapor that penetrates coalescing media, completely removing oily odor and organic volatile contaminants to protect high-end production products and precision equipment.

Large-capacity encapsulated carbon core for long stable service life

High-filling volume coconut shell activated carbon provides massive adsorption capacity. Front microglass pre-layer intercepts residual liquid oil before contacting carbon, avoiding premature carbon poisoning and extending service cycle.

Fully sealed anti-carbon-powder-shedding structure, no pipeline secondary pollution

Carbon filling layer fully wrapped by stainless steel mesh and white foam, no carbon powder shedding under long-term large airflow; prevents blockage and carbon contamination of large spray manifolds, laser optical lenses and cleanroom piping.

Low-loss flow channel design reduces large compressor energy consumption

Smooth graded internal flow structure minimizes airflow resistance under full rated flow, low dry-state pressure loss reduces continuous running load of large screw/centrifugal compressors and cuts factory electricity costs.

Working Principle

Dry pre-purified large-volume compressed air flows through cartridge outside-in:

Front microglass interception layer traps residual tiny liquid oil droplets and fine solid particles carried from upstream PD filter;

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

Outer stainless steel mesh prevents foam abrasion and carbon powder from flowing into downstream piping;

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

Application Industries

Full automobile factory electrostatic spray production lines, heavy industry large-format laser cutting workshops, pharmaceutical factory central aseptic filling air supply, large electronics cleanroom main gas source, food & beverage giant sterile packaging plants, multi-station heavy automation production lines requiring strict Class 0 oil-free compressed air.
