Key Product Features

Deep Polishing Ultra-fine Oil Mist Removal

After coarse particulate and medium coalescing pre-filtration, this element captures invisible trace submicron oil aerosol and residual tiny condensate droplets that medium filters cannot fully trap. It delivers near oil-free compressed air and drastically slows saturation of downstream activated carbon filter elements to extend their service cycle.

Low Pressure Drop Energy-saving Design

Optimized deep-pleated glass fiber media maximizes effective filtration area. Stable low airflow resistance is maintained under 24-hour full-load continuous operation, cutting extra power consumption of air compressors and reducing overall factory air supply operating costs.

Extra Large Dirt & Oil Holding Capacity

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

Reinforced Plastic Anti-breakage Support Cage

Inner and outer plastic frames withstand high-speed airflow impact, prevent filter media collapse, deformation and fiber shedding, and eliminate secondary fiber contamination of clean compressed air.

Working Principle

Compressed air pre-treated by coarse and medium filters flows into the cartridge from the outer plastic protective frame. The multi-layer ultra-fine glass fiber medium captures 0.01 μm submicron oil mist particles, which collide and coalesce into large liquid droplets. Liquid condensate sinks to the housing bottom drain port and discharges automatically by gravity. Ultra-clean low-oil compressed air flows to activated carbon filters or high-standard precision production equipment.

Application & Industries

Serves as the core ultra-precision polishing filter in industrial compressed air purification systems, installed between medium coalescing filters and activated carbon filters.

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