Key Product Advantages

Final-stage adsorption filter to deliver fully oil-free, odorless compressed air

Installed as the last purification stage after Y ultrafine coalescer, this Z-grade carbon element removes gaseous oil vapor and persistent oily odors that glass fiber coalescing media cannot capture. Silicone-free media eliminates paint pinhole and fogging defects for automotive topcoat spraying production lines.

High carbon adsorption capacity & stable service life

High-specific-surface-area activated carbon foam provides strong adsorption performance for mineral oil vapor and hydrocarbon gases, maintaining stable purification effect in medium-humidity workshop environments and reducing unplanned downtime for filter replacement.

Optimized airflow path to cut long-term compressor energy consumption

Flow-oriented folded composite media minimizes airflow resistance, avoiding excessive pipeline pressure loss that increases air compressor motor power draw, lowering overall factory electricity operating costs.

Corrosion-resistant stainless steel support cage

Double-layer stainless steel inner/outer cages prevent media collapse under full-load airflow; durable rubber seal resists aging from lubricant oil and condensed water, ensuring permanent airtight sealing without air bypass.

Push-in quick-swap installation without full housing disassembly

Working Principle

Purified compressed air from Y ultrafine coalescer flows outside-in through the cartridge:

The front glass fiber layer traps residual tiny oil mist and fine solid contaminants;

Air penetrates the high-density activated carbon foam layer; gaseous oil vapor, volatile organic compounds and odor molecules are fully captured by carbon micropores;

Clean, dry, odorless and oil-free compressed air flows out from the inner support tube to terminal precision production equipment;

Trace condensed liquid oil captured by the front filter layer drains down to the filter bowl by gravity and automatic drain valve.

Application Industries

Automotive electrostatic spray booths, small laser cutting machines, pharmaceutical sterile filling cleanroom lines, food aseptic packaging, PCB laboratory manufacturing, precision analytical instruments, medical breathing air pretreatment, small standalone air compressor stations, solvent coating production lines, miniature high-precision pneumatic automation equipment, post-filter for small adsorption dryers to eliminate residual oil vapor.
