Key Product Features

Final-Stage Deep Purification for Oil Vapor & Odor Elimination

Must be installed downstream of PD180+ superfine coalescing filter. It captures invisible gaseous oil vapor and unpleasant odors that glass fiber coalescing media cannot intercept, delivering fully oil-vapor-free, odorless ultra-clean compressed air to satisfy strict high-end production requirements.

Low Pressure Drop & Energy Saving

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

Strong Adsorption & Contaminant Holding Capacity

Front gradient glass fiber barrier traps residual liquid oil mist to prevent rapid saturation of carbon bed; thick high-purity coconut shell activated carbon provides massive adsorption capacity, extending maintenance intervals and minimizing production downtime during element replacement.

Heavy-Duty Stainless Steel Anti-Powder Reinforcement Cage

Dual stainless steel mesh cages resist high-speed airflow impact, preventing media deformation and carbon powder shedding to avoid secondary contamination of terminal precision equipment.

Working Principle

Compressed air after multi-stage oil & water pre-treatment by DD and PD elements enters the cartridge from the outer stainless steel protective mesh. The outer glass fiber layer intercepts tiny residual liquid oil droplets; the internal high-density activated carbon bed fully adsorbs gaseous oil vapor, hydrocarbon odors and organic volatile substances. 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, only installed downstream of PD-grade superfine coalescing filters.

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