Key Product Features

Terminal Deep Polishing Oil Mist Removal

After coarse and medium coalescing filtration, this element intercepts trace ultra-fine oil aerosol, micro dust and residual tiny water droplets that cannot be fully captured by Grade G filters. It delivers near oil-free compressed air and protects downstream activated carbon filters from rapid saturation to extend their service cycle.

Low Pressure Drop Energy-saving Structure

Uniform deep-folded glass fiber media provides large effective filtration area. It maintains stable low airflow resistance under long-term full-load continuous operation, cuts idle power consumption of air compressors and lowers overall plant air supply operation costs.

High Dirt & Oil Holding Capacity

Multi-layer gradient depth filtration structure stores large amounts of separated lubricating oil and micro contaminants, prolongs maintenance intervals and reduces shutdown & replacement frequency.

Perforated Stainless Steel Inner Support Cage

Resists impact of high-velocity airflow, prevents filter media collapse and fiber shedding, and avoids secondary fiber contamination of clean air, suitable for 24-hour continuous industrial operation.

Working Principle

Compressed air pre-treated by Grade S and Grade G filters flows into the element from the outer surface. The multi-layer ultra-fine glass fiber medium captures 0.01 μm submicron oil mist particles, which collide and coalesce into large liquid droplets. The liquid droplets sink to the bottom drain port of the filter housing by gravity and are automatically discharged. Ultra-clean low-oil compressed air flows to activated carbon filters or high-standard terminal production equipment.

Application & Industries

Serves as the core ultra-precision polishing filter in compressed air purification systems, installed between Grade G 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.
