Key Product Features

Deep Polishing Ultra-Fine Oil Mist Removal

Installed after Grade G medium coalescing pre-filter, this cartridge captures invisible trace submicron oil aerosols and tiny residual condensed water droplets that medium-grade filters cannot fully intercept. It produces nearly oil-free compressed air and significantly slows saturation of downstream Grade A activated carbon filter elements to extend their overall service cycle.

Low Pressure Drop & Energy Saving

Deep-pleated proprietary glass fiber media maximizes effective filtration area remarkably. It maintains stable low airflow resistance under 24-hour full-load continuous operation, reduces extra power consumption of air compressors and cuts overall factory air supply operating costs.

Large Dirt & Oil Holding Capacity

Multi-gradient layered depth filtration structure stores massive separated lubricating oil, condensed water and micro solid contaminants, extending maintenance intervals and minimizing production downtime during filter replacement.

Heavy-Duty Stainless Steel Reinforced Support Cage

Dual stainless steel mesh cages resist strong high-speed airflow impact under heavy-duty industrial conditions, preventing filter media collapse, deformation and fiber shedding to eliminate secondary fiber contamination of clean compressed air.

Working Principle

Compressed air pre-treated by Grade G medium filter enters the cartridge from the outer stainless steel protective mesh. Multi-layer ultra-fine glass fiber captures 0.01 μm submicron oil mist particles; tiny oil droplets continuously collide and coalesce into large liquid condensate, which sinks to the filter housing bottom and drains automatically by gravity. Ultra-clean low-oil compressed air is delivered to activated carbon filters or high-precision terminal production equipment.

Application & Industries

Core ultra-precision polishing filter for large-flow industrial compressed air post-processing systems, installed between medium coalescing filters and activated carbon filters.

Widely applied in heavy automotive production lines, precision electronic assembly, pharmaceutical mass aseptic manufacturing, food sterile packaging, medical equipment processing, optical coating, laboratory analytical instruments, automotive topcoat spraying, heavy-duty laser cutting and factory centralized large-flow air supply systems requiring Class 1 ultra-clean oil-free compressed air.
