Key Product Features

Deep Polishing Ultra-Fine Oil Mist Removal

Installed downstream of F1440IG general pre-filter, this red high-efficiency cartridge captures invisible trace submicron oil aerosols and tiny residual condensed water droplets that 1μm coarse filters cannot fully intercept. It delivers nearly oil-free compressed air and drastically reduces contaminant load to extend the service life of downstream 88292004-007 F1440IA activated carbon elements.

Low Initial Differential Pressure & Energy Saving

Deep-pleated proprietary glass fiber media maximizes effective filtration surface area. Optimized smooth bore flow design eliminates air turbulence, maintaining stable low airflow resistance under 24/7 full-load continuous operation, reducing extra power consumption of air compressors and cutting long-term factory operating costs.

Large Dirt & Oil Holding Capacity

Thick gradient glass fiber matrix stores massive coalesced lubricant oil, condensed water and metal wear debris, greatly extending maintenance intervals and minimizing production downtime during element replacement.

Heavy-Duty Stainless Steel Reinforced Support Cage

Dual stainless steel mesh cages resist violent turbulent airflow inside the filter housing, preventing media bulging, rupture and fiber shedding to eliminate secondary contamination of downstream precision air equipment.

Working Principle

Compressed air pre-treated by F1440IG coarse filter enters the cartridge from the outer stainless steel protective mesh. Multi-layer ultra-fine glass fiber traps 0.01μm oil mist aerosols; tiny oil droplets continuously collide and aggregate into liquid oil beads, which flow down the inner wall of the cartridge by gravity and drain automatically from the filter housing drain port. Ultra-clean low-oil compressed air flows forward to F1440IA activated carbon filter for oil vapor and odor removal.

Application & Industries

Core precision polishing filter for large-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 equipment processing, optical coating, laboratory analytical instruments, automotive topcoat electrostatic spraying, heavy-duty laser cutting and factory centralized compressed air supply stations requiring Class 1 ultra-clean oil-free compressed air.
