Key Product Features

Deep Polishing Ultra-fine Oil Mist Removal

After coarse pre-filter and medium coalescing filter treatment, this element captures invisible trace submicron oil aerosol and tiny residual water droplets that cannot be fully trapped by Grade G filters. It delivers nearly oil-free compressed air and effectively protects downstream activated carbon filters from fast saturation to extend their service cycle.

Low Pressure Drop Energy-saving Design

Optimized deep pleated glass fiber media expands the effective filtration area significantly. It maintains stable low airflow resistance under long-term 24-hour full-load continuous operation, cuts extra power consumption of air compressors and reduces overall plant air supply operating costs.

Extra Large Dirt & Oil Holding Capacity

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

Double 304 Stainless Steel Perforated Support Cage

Inner and outer metal mesh 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-cleaned by Grade X and Grade G filters flows into the cartridge from the outer mesh 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. Liquid droplets sink to the housing bottom drain port and discharge 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 large-flow compressed air purification systems, installed between medium coalescing filters and activated carbon filters.

Widely used in automotive manufacturing, precision electronic assembly, pharmaceutical production, food packaging, medical equipment, optical coating, laboratory instruments, automotive topcoat painting, heavy-duty laser cutting and large factory centralized high-flow compressed air supply systems requiring Class 1 ultra-clean compressed air.
