Key Product Features

Deep Polishing Ultra-fine Oil Mist Removal

After QF pre-filter and PF medium coalescing pre-treatment, this element intercepts invisible trace submicron oil aerosol and residual tiny condensed water droplets that medium filters cannot fully capture. It delivers nearly 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 remarkably. It maintains stable low airflow resistance under long-term 24-hour full-load continuous operation, cuts extra power consumption of air compressors and lowers 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

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

Working Principle

Compressed air pre-treated by QF and PF filters flows into the cartridge from the outer red glass fiber layer. 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 automatic 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 aseptic packaging, medical equipment processing, optical coating, laboratory analytical instruments, automotive topcoat spraying, heavy-duty laser cutting and factory centralized compressed air supply systems requiring Class 1 ultra-clean compressed air.
