Key Product Advantages

Ultra-pure air finishing to eliminate oil vapor and peculiar smell

Dense activated carbon block adsorbs invisible oil vapor and hydrocarbon odor that cannot be intercepted by coalescing filters. It provides oil-free, odor-free high-purity compressed air for high-standard production processes.

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 compressor power consumption and long-term operation cost.

Large activated carbon storage capacity to extend maintenance cycle

Massive high-activity carbon filling ensures long adsorption life, not easy to saturate even under long-term trace oil vapor environment, reducing replacement frequency.

Integrated anti-shedding carbon block structure

Integrally molded carbon block with front glass fiber pre-filter, effectively prevent carbon powder from flowing into downstream pipelines and causing equipment contamination.

Working Principle

Compressed air after two-stage pre-filtration and coalescing treatment enters the activated carbon filter cartridge. Trace oil vapor and organic odor molecules are fully adsorbed by the high-specific-surface activated carbon block. Final oil-free, odorless clean compressed air flows out for precision production equipment use.
