Key Product Advantages

Low Initial Differential Pressure for Energy Saving

Deep-pleated glass fiber media expands effective filtration area and optimizes internal airflow channels to eliminate turbulence. Stable low pressure loss is maintained under 24/7 full-load continuous operation, cutting extra power consumption of air compressors and lowering 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, greatly extending maintenance intervals and minimizing production downtime caused by frequent element replacement.

Heavy-Duty Reinforced Anti-Delamination Cage

Dual anti-rust metal mesh cages resist 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 AE058AO coarse filter enters the cartridge from the outer metal 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 the inner wall of the cartridge by gravity and drain automatically via the housing float drain port. Ultra-clean low-residual-oil compressed air flows forward to AC058ACS activated carbon filter for oil vapor removal.

Application & Industries

Core precision polishing filter for 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 analytical instruments, automotive electrostatic topcoat spraying, laser cutting and centralized factory compressed air supply stations requiring Class 1 ultra-clean oil-free compressed air.
