Key Product Advantages

Ultimate Deep Purification to Eliminate Invisible Gaseous Oil Vapor

Installed downstream of 50075S high-efficiency coalescing filter, this black carbon cartridge captures gaseous oil vapor that glass fiber coalescing media cannot intercept. High-specific-surface-area coconut shell activated carbon fully adsorbs organic volatiles and oily odors, meeting strict zero oil-vapor requirements for automotive topcoat painting, semiconductor assembly, pharmaceutical and food-grade production. Silicon-free version is optional for high-gloss painting lines to avoid paint surface defects.

Dual Anti-Leakage Structure Prevents Downstream Carbon Powder Contamination

Front hydrophobic foam intercepts residual tiny liquid oil droplets; built-in fine stainless steel baffle blocks fine carbon powder from flowing to production equipment and finished goods, eliminating black speck defects on product surfaces.

Large Carbon Filling Volume Extends Maintenance Intervals

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

Hydrolysis & Temperature Resistant Stable Construction

Acid-alkali resistant activated carbon matched with stainless steel support frame; the medium will not pulverize under long-term humid compressed air operation, avoiding secondary pipeline contamination to precision valves and processing equipment.

Working Principle

Dry low-oil compressed air discharged from 50075S high-efficiency coalescing filter flows outside-in through the cartridge:Front hydrophobic foam layer traps 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, oil-vapor-free compressed air flows out from the inner core to downstream precision production equipment.
