Key Product Advantages

Final deep purification to eliminate oil vapor for ultra-clean compressed air

Installed after DD310+ coalescing filter, this carbon element removes gaseous oil vapor that liquid coalescing media cannot capture. High-specific-surface-area coconut shell carbon fully adsorbs organic volatiles and unpleasant odors, meeting zero oil-vapor requirements for precision manufacturing, spraying and laboratory applications.

Integrated double anti-leakage structure, no carbon powder downstream carryover

Front hydrophobic foam intercepts residual micro liquid oil droplets; built-in fine stainless steel baffle prevents activated carbon fine powder from contaminating downstream equipment and finished products.

Large carbon filling volume extends maintenance cycles

Adequate carbon bed storage delays vapor saturation, reduces frequent replacement frequency and labor costs for medium-flow air compressor stations.

Hydrolysis & temperature resistant construction for stable long-term operation

Acid/alkali resistant activated carbon matched with stainless steel support frame, no medium pulverization under humid compressed air conditions, avoids secondary pipeline pollution.

Working Principle

Dry, low-oil compressed air discharged from DD coalescing filter flows outside-in through the cartridge:

Front hydrophobic foam layer intercepts residual tiny liquid oil droplets;

Air penetrates dense coconut shell activated carbon bed, oil vapor and organic gaseous pollutants are physically adsorbed by carbon micropores;

Clean, odor-free compressed air flows out from inner core to downstream precision production equipment.

Application Industries

widely applied in:

Ordinary & high-gloss automotive spray booths, pharmaceutical sterile cleanrooms, food aseptic filling packaging, electronic component assembly, laboratory precision analytical instruments, medium-scale factory centralized compressed air stations, solvent spraying production lines, small medical breathing air pretreatment.
