Key Product Advantages

Core Ultra-Clean Polishing Stage for Zero-Oil Critical Production

Installed downstream of 88343298 particulate prefilter, this red Grade6 cartridge intercepts invisible trace 0.01μm submicron oil/water aerosols that prefilter cannot fully separate. It drastically reduces trace liquid oil load on terminal activated carbon filter, extends carbon service life and lowers overall system maintenance cost. Silicon-free formula optional for automotive painting lines to eliminate paint pinhole defects.

Ultra-Large Liquid Holding Capacity for High-Humidity Workshop Environments

Thick multi-gradient pleated micro glass fiber matrix provides massive oil & water storage volume, resisting rapid saturation in factories with insufficient aftercooler or refrigerated dryer performance. Widely used before desiccant dryers to protect dryer molecular sieve from oil contamination.

Low Flow Resistance for Energy Saving

Deep-pleated micro glass fiber maximizes effective filtration area, maintaining ultra-stable low pressure drop under 24/7 full-load continuous operation, lowering extra power consumption of medium air compressor stations.

Hydrolysis & Abrasion Resistant Fiber-Free Construction

Oil-repellent borosilicate micro glass fiber matched with stainless steel support cage prevents fiber shedding under long-term humid compressed air impact, eliminating secondary pipeline contamination to downstream precision processing equipment.

Working Principle

Pre-cleaned compressed air from particulate prefilter flows outside-in through the cartridge:

Residual bulk liquid water and fine solid particles are blocked by outer red hydrophobic foam;

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

Outer red 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 and automatic drain valve;

Application Industries
