Key Product Features

Ultra-Fine Oil Mist Deep Polishing

Installed after Grade M medium coalescing filter, this element captures invisible trace submicron oil aerosols and tiny residual condensed water droplets that medium-grade filters cannot fully trap. It delivers nearly oil-free compressed air and drastically slows saturation of downstream Grade A activated carbon filter elements to extend their service cycle.

Low Pressure Drop & Energy Saving

Deep-pleated 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 lowers 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.

Anti-Deformation Reinforced Plastic Support Cage

Internal perforated plastic frame withstands high-speed airflow impact, prevents filter media collapse, deformation and fiber shedding to avoid secondary fiber contamination of clean compressed air.

Working Principle

Compressed air pre-treated by Grade R and Grade M filters flows into the cartridge from the outer glass fiber layer. The multi-layer ultra-fine glass fiber medium 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 then delivered to activated carbon filters or high-precision terminal production equipment.

Application & Industries

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

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