Key Product Advantages

Final-stage adsorption barrier to supply fully oil-free, odorless compressed air for high-sensitivity processes

Installed downstream of F-grade ultrafine coalescing filter, this A cartridge adsorbs gaseous oil vapor which cannot be trapped by mechanical glass fiber coalescing media. It completely removes oily odors and volatile hydrocarbon pollutants to protect downstream precision equipment, finished product quality and cleanroom production environments.

High-specific-surface-area activated carbon foam with long-lasting adsorption capacity

Uniform high-porosity carbon foam matrix provides massive adsorption volume, extending service intervals and resisting rapid saturation under oil-contaminated pipeline conditions. The built-in upstream microfiber layer traps residual liquid oil mist before contacting carbon media, avoiding premature carbon deactivation.

Integrated anti-carbon-shedding design, no secondary pipeline pollution

Activated carbon foam is fully encapsulated inside a stabilizing support structure, paired with full stainless steel outer shielding mesh. Zero carbon dust leakage under long-term medium-flow airflow impact, preventing blockage and contamination of laser optical lenses, fine spray nozzles, electronic circuit boards and food/pharmaceutical raw materials.

Optimized internal flow path for low permanent pressure loss

Built-in inlet flow distributor minimizes airflow turbulence, maintaining stable low pressure drop throughout the whole service cycle. Lower system backpressure reduces continuous power consumption of medium screw air compressors and cuts long-term factory electricity operating costs.

Working Principle

Pre-polished clean compressed air flows through the filter cartridge from outside to inside:

The front integrated micro glass fiber interception layer traps residual tiny liquid oil droplets and fine solid particles carried over from the upstream ultrafine coalescer;

Purified gas penetrates the high-density activated carbon foam core; gaseous oil vapor, volatile organic compounds and odor molecules are permanently adsorbed onto carbon micropores;

Stainless steel outer protective mesh prevents carbon foam abrasion and carbon powder from entering downstream piping;

Dry, odorless, oil-vapor-free compressed air flows out from the inner stainless steel supporting tube and feeds terminal sensitive production equipment.
