Key Product Features

Ultra-Fine Submicron Oil Mist Coalescing Performance

Installed downstream of general grade pre-filter, this element captures invisible nanoscale oil aerosols and tiny residual condensed water that coarse filters cannot intercept. It drastically cuts lubricant carryover and protects downstream activated carbon elements from rapid saturation and premature failure.

Low Initial Differential Pressure & Energy Saving

Deep-pleated glass fiber media maximizes effective filtration surface area and optimizes internal flow channels to eliminate air turbulence. Stable low pressure drop under 24/7 full-load continuous operation reduces compressor power consumption and long-term factory operation costs.

Extra 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 filter replacement.

Heavy-Duty Anti-Deformation Reinforcement Cage

Dual metal 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 general pre-filter enters the cartridge from 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, 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 activated carbon filter for oil vapor removal.

Application & Industries

High precision coalescing filter for industrial compressed air post-processing systems, installed downstream of general pre-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, laser cutting and factory centralized compressed air supply stations requiring Class 1 ultra-clean oil-free compressed air.
