Key Product Advantages

Final purification to realize oil-free & odor-free compressed air

Coalescing filters can only intercept liquid oil droplets, invisible gaseous oil vapor will pass through. This AU carbon block uses high-activity coconut shell carbon with huge specific surface area to fully adsorb oil vapor and peculiar smell, providing ultra-pure compressed air for high-precision production.

Low initial pressure drop for energy saving

Optimized internal flow channel design, stable low pressure loss under 24/7 full-load continuous operation, effectively reduce long-term compressor power consumption.

Large carbon filling capacity to extend maintenance cycle

Sufficient high-quality activated carbon filling, strong adsorption capacity, not easy to saturate under long-term trace oil vapor environment, reduce replacement frequency.

Anti-shedding integrated carbon block structure

Front microglass pre-filter intercepts fine dust first, the integrally molded carbon block avoids carbon powder falling off and polluting downstream pipelines, no secondary contamination to equipment.

Working Principle

Compressed air after three-stage pre-filtration (dust + liquid oil removal) flows through the front glass fiber pre-layer to block residual fine particles, then fully contacts the activated carbon block. Gaseous oil vapor, hydrocarbon odor molecules are physically adsorbed by carbon pores. Finally oil-free, odorless ultra-clean compressed air is output for precision equipment.
