Key Product Advantages

Intermediate polishing stage to protect high-cost downstream precision filters

Installed after FC P particulate prefilter, this X-grade blue element traps bulk condensed water, coarse oil droplets and 1 μm fine liquid aerosols that pass the primary dust filter. It greatly reduces liquid contamination load on Y ultrafine coalescer and Z activated carbon cartridges, extends their service life and cuts overall system maintenance cost.

Large liquid holding capacity for high-humidity workshop environments

Thick deep-pleated gradient glass fiber matrix holds massive volumes of condensed oil and condensate, avoiding rapid saturation in facilities with underperforming aftercoolers or refrigerated dryers.

Low airflow resistance to save long-term compressor energy cost

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

Hydrolysis & abrasion resistant media with no fiber shedding

Oleophobic borosilicate glass fiber combined with stainless steel support cage prevents fiber detachment under long-term humid compressed air impact, eliminating secondary pipeline contamination to downstream pneumatic valves and general processing equipment.

Working Principle

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

Bulk condensed water and large solid particles are blocked by outer blue hydrophobic foam layer;

Medium-sized oil & water aerosols collide and coalesce into large liquid droplets through multi-layer gradient borosilicate glass fiber media;

Outer anti-re-entrainment foam prevents coalesced liquid droplets from being blown back into high-speed airflow;

Separated oil and condensate drain down to the filter bowl by gravity and automatic drain valve;

Medium-clean dry compressed air flows downstream to Y ultrafine coalescer for advanced precision polishing treatment.
