Key Product Advantages

Final deep purification to eliminate invisible gaseous oil vapor

Installed downstream of KTF high-efficiency coalescing filter, this carbon cartridge captures gaseous oil vapor that liquid glass fiber media cannot intercept. High-iodine-value coconut shell activated carbon fully adsorbs organic volatiles and oily odors, satisfying strict zero oil-vapor standards for automotive topcoat painting, semiconductor, pharmaceutical and food production.

Double-layer anti-leakage structure to avoid carbon powder downstream contamination

Front hydrophobic foam intercepts residual micro liquid oil droplets; built-in fine stainless steel baffles block fine carbon powder from flowing to production equipment and finished goods, eliminating black speck defects on product surface. Silicon-free version available for high-gloss automotive painting lines.

Large carbon filling volume extends maintenance cycles

Thick integrated carbon bed storage delays vapor saturation, reduces frequent replacement frequency and labor maintenance cost for large central air compressor stations.

Hydrolysis & temperature resistant stable construction

Acid-alkali resistant activated carbon matched with stainless steel support frame; medium will not pulverize under long-term humid compressed air operation, no secondary pipeline pollution.

Working Principle

Front hydrophobic foam layer traps 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, oil-vapor-free compressed air flows out from inner core to downstream precision production equipment.

Application Industries

Automotive group central electrostatic painting workshops, multi-line large laser cutting equipment, pharmaceutical sterile cleanrooms, food large-batch aseptic filling & packaging, electronic PCB & chip assembly, laboratory precision analytical instruments, large factory centralized air compressor stations, solvent spraying production lines, medical breathing air pretreatment.
