Key Product Advantages

Deep Capture of Invisible Submicron Oil Mist for Critical Precision Processes

Installed downstream of 9.9680.0 KA particulate prefilter, this KB grade white element intercepts invisible 0.01μm ultra-fine oil & water aerosols that general coalescing media cannot fully separate. The outer white hydrophobic foam eliminates secondary liquid re-entrainment; coalesced oil and moisture drain rapidly to the filter bowl, delivering ultra-low residual oil compressed air for strict critical production processes. Silicon-free variants are optional for automotive topcoat painting lines to avoid paint surface speck defects.

Deep-Pleated Low-DP Media for Energy Saving

Optimized deep-fold gradient micro glass fiber maximizes effective filtration area, maintaining ultra-stable low pressure drop under 24/7 full-load continuous operation, drastically cutting long-term power consumption of medium & large central air compressor units.

Extra-Large Liquid Holding Capacity Extends Maintenance Intervals

Thick multi-gradient hydrophobic fiber matrix provides massive oil & water storage volume, resisting rapid saturation under high-humidity, high-oil workshop environments and reducing frequent replacement labor and spare parts procurement costs.

Hydrolysis & Abrasion Resistant Fiber-Free Construction

Oleophobic borosilicate micro glass fiber paired with stainless steel support mesh prevents fiber shedding under long-term humid compressed air operation, eliminating secondary pipeline contamination to downstream precision equipment and finished products.

Working Principle

Micro oil & water aerosols collide and coalesce into large liquid droplets across multi-layer gradient borosilicate micro glass fiber media;

Outer white anti-re-entrainment foam sleeve stops coalesced liquid droplets from being re-carried by high-speed airflow;

Condensed oil and water drain down to the filter bowl by gravity;

Ultra-dry, ultra-low-oil compressed air is delivered to downstream KE ultra-fine filter or high-precision production equipment.

Application Industries

Automotive high-gloss electrostatic painting workshops, multi-line large laser cutting equipment, pharmaceutical sterile cleanrooms, food large-batch aseptic filling & packaging, PCB & semiconductor chip assembly, laboratory precision analytical instruments, medical breathing air pretreatment, medium & large factory centralized air compressor stations, solvent spraying production lines, full-automatic high-precision pneumatic automation production lines.
