Key Product Advantages

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

Installed after DD+ coalescing filter, this QD+ carbon element removes gaseous oil vapor that liquid coalescing filters cannot capture. Large specific surface area coconut shell carbon fully adsorbs organic volatiles and unpleasant odors, meeting zero oil-vapor requirements for high-end production.

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

Front coalescing foam intercepts residual micro oil droplets; built-in fine-mesh stainless steel baffles prevent activated carbon powder from flowing downstream to contaminate equipment and finished products.

Large carbon filling capacity extends adsorption service cycle

Ample carbon bed storage volume delays vapor saturation, reduces frequent replacement frequency and maintenance labor costs for large-flow central air compressor stations.

Working Principle

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

Front hydrophobic foam layer intercepts residual micro 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 the inner core to downstream precision production equipment.

Application Industries

widely applied in:

Automotive high-gloss electrostatic painting workshops, pharmaceutical sterile cleanrooms, food aseptic filling packaging, electronic chip & semiconductor assembly, laboratory precision analytical instruments, large centralized factory compressed air stations, solvent spraying production lines, medical breathing air pretreatment.
