Key Product Advantages

Deep-Pleated Low-DP Media for Energy Saving

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

Large Liquid Holding Capacity Extends Maintenance Intervals

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

Hydrolysis & Abrasion Resistant Fiber-Free Construction

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

Working Principle

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

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

Outer green 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;

Dry, low-oil compressed air is delivered to downstream FF ultra-fine filter or general precision production equipment.

Application Industries

General metal machining workshops, textile printing equipment, packaging printing machinery, small auto repair spray booths, low-demand laboratory instruments, medium factory centralized air compressor stations, ordinary full-automatic pneumatic automation production lines, general food packaging equipment.
