Key Product Advantages

Low Initial Differential Pressure & Energy Saving

Optimized layered composite structure maximizes effective adsorption area and smooth airflow channels, maintaining stable low airflow resistance under 24/7 full-load continuous operation. It reduces extra power consumption of air compressors and cuts long-term factory air supply operating costs.

Powerful Adsorption & Contaminant Holding Capacity

The front gradient glass fiber barrier blocks residual liquid oil mist to prevent premature saturation of the carbon bed. Thick high-purity coconut shell activated carbon provides massive adsorption capacity, extending maintenance intervals and minimizing production downtime caused by element replacement.

Heavy-Duty Anti-Powder Reinforcement Cage

Dual metal mesh cages withstand violent high-speed turbulent airflow inside filter housing, preventing media deformation, rupture and carbon powder shedding to avoid secondary contamination of downstream precision terminal equipment.

Working Principle

Compressed air pre-treated by P-grade pre-filter and B-grade coalescing filter enters the cartridge from the outer metal protective mesh. The outer glass fiber interception layer traps tiny residual liquid oil droplets; the internal high-density activated carbon bed fully adsorbs gaseous oil vapor, hydrocarbon odors and volatile organic compounds. Pure, oil-vapor-free and odorless compressed air flows out from the central pipeline to high-standard production equipment.

Application & Industries

Terminal adsorption filter for medium-flow industrial compressed air post-processing systems, exclusively installed downstream of high-efficiency coalescing filters.

Widely applied in pharmaceutical aseptic manufacturing, food sterile packaging, precision electronic assembly, medical device processing, optical coating, laboratory analytical instruments, automotive electrostatic topcoat spraying, laser cutting and centralized factory compressed air supply stations requiring Class 1 ultra-pure oil-free compressed air.
