Key Product Features

Terminal Deep Oil Polishing

After pre-filtration by Grade P coarse filter and Grade G medium coalescing filter, this element captures trace invisible submicron oil aerosols and tiny residual condensed water droplets that standard filters cannot trap. It produces nearly oil-free compressed air and significantly slows saturation of downstream activated carbon elements to extend their service life.

Low Pressure Drop & Energy Saving

Deep-pleated glass fiber media greatly expands effective filtration area. 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 lubricating oil, condensed water and solid contaminants, extending maintenance intervals and minimizing production downtime during filter replacement.

Impact-resistant Reinforced Support Frame

Dual anti-corrosion plastic cages withstand high-speed airflow impact, preventing media collapse, deformation and fiber shedding to avoid secondary fiber contamination of clean compressed air.

Working Principle

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

Application & Industries

Core ultra-precision polishing filter for 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, heavy-duty laser cutting and factory centralized large-flow air supply systems requiring Class 1 ultra-clean oil-free compressed air.
