Key Product Advantages

It drastically reduces liquid contamination load on QD850F ultrafine coalescer and QD+ activated carbon cartridges, extends their service life and cuts overall system maintenance & spare parts expenditure.

Extra-large liquid holding capacity for high-humidity heavy industrial environments

Thick deep-pleated gradient glass fiber matrix stores massive volumes of condensed oil and condensate, resisting rapid saturation in large factories with underperforming aftercoolers or refrigerated dryers.

Low permanent airflow resistance to reduce central compressor station energy consumption

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

Hydrolysis & abrasion resistant media with zero fiber shedding

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

Exclusive 4-hole bayonet quick-swap design without full housing disassembly

Unique 4-hole central positioning metal mandrel perfectly locks into DD850+F flanged filter housings; a single operator can complete cartridge replacement within 3 minutes without removing the entire heavy filter tank body.

Working Principle

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

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

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

Application Industries

Large metal machining workshops, heavy metal forging plants, sandblasting workshops, textile printing factories, large packaging printing equipment, medium & large factory centralized screw compressor stations, construction machinery air supply systems, full-automatic large pneumatic automation production lines, heavy-duty laser cutting equipment, food & beverage mass production workshops.
