Key Product Features

Ultra-Low Initial Differential Pressure & Energy Saving

Deep-pleated nano glass fiber media maximizes effective filtration area, optimizes internal flow channels to eliminate air turbulence. Stable minimal pressure drop under 24/7 full-load continuous operation, greatly reducing compressor power consumption and long-term factory operation cost.

Extra Large Dirt & Oil Holding Capacity

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

Heavy-Duty Stainless Steel Anti-Deformation Reinforcement Cage

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

Working Principle

Raw compressed air pre-treated by DD coarse filter enters the UD cartridge from outer stainless steel protective mesh. Multi-layer nano glass fiber medium intercepts 0.001μm ultra-fine oil mist and solid particles. Tiny oil droplets continuously collide, 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 QD activated carbon filter for oil vapor removal.

Application & Industries

Top-grade ultra-high precision coalescing filter for large-flow industrial compressed air post-processing systems, installed downstream of DD general filters.

Widely applied in pharmaceutical aseptic manufacturing, food sterile packaging, precision electronic assembly, medical equipment processing, optical coating, laboratory analytical instruments, automotive electrostatic topcoat spraying, heavy-duty laser cutting and factory centralized compressed air supply stations requiring Class 0 ultra-clean oil-free compressed air.
