 Key Product Features

Low Initial Differential Pressure & Energy Saving

Deep-pleated large-area glass fiber media optimizes internal airflow channels to eliminate turbulence, maintaining stable low pressure loss under 24/7 full-load continuous operation. It cuts extra power consumption of air compressors and lowers long-term factory air supply operating costs.

Large Dirt & Liquid Holding Capacity

Thick gradient depth fiber matrix stores massive coalesced lubricant oil, condensed water and metal wear sludge, significantly extending maintenance intervals and minimizing production downtime caused by frequent element replacement.

Heavy-Duty Stainless Steel Reinforcement Cage

Dual stainless steel mesh cages withstand violent high-speed turbulent airflow inside filter housing, preventing media bulging, rupture and fiber shedding to avoid secondary contamination of downstream precision terminal equipment.

Working Principle

Compressed air pre-treated by AO/AR coarse filter enters the cartridge from the outer stainless steel protective mesh. Multi-layer ultra-fine glass fiber medium intercepts 0.01μm oil mist aerosols and solid particles. Tiny oil droplets continuously collide and aggregate into large liquid oil beads, flow down cartridge inner wall by gravity and drain automatically via housing drain port. Ultra-clean low-residual-oil compressed air flows forward to optional ACS activated carbon filter for oil vapor removal.

Application & Industries

Core precision polishing filter for small/medium-flow industrial compressed air post-processing systems, installed between general coalescing pre-filters and activated carbon filters.

Widely applied in pharmaceutical aseptic manufacturing, food sterile packaging, precision electronic assembly, medical & dental equipment, optical coating, laboratory instruments, automotive electrostatic topcoat spraying, laser cutting and centralized factory compressed air supply stations requiring Class 1 ultra-clean oil-free compressed air.
