Key Product Advantages

It drastically reduces trace liquid oil contamination load on terminal QD+ activated carbon cartridges, extends carbon service life and cuts overall system maintenance & spare parts expenditure. Silicone-free media eliminates paint pinhole and fogging defects for automotive topcoat spraying workshops.

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

Thick deep-pleated gradient micro glass fiber matrix stores massive volumes of condensed oil and condensate, resisting rapid saturation in large factories with underperforming aftercoolers or refrigerated dryers. Widely installed upstream of large adsorption dryers to protect molecular sieve media from permanent oil fouling.

Optimized low airflow resistance to cut central compressor station energy consumption

Uniform deep-fold micro glass fiber maximizes effective filtration area, maintaining ultra-stable low pressure drop under 24/7 continuous full-load large-volume operation, minimizing extra power draw of large air compressor units and long-term electricity costs.

Hydrolysis & abrasion resistant media with zero fiber shedding

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

Working Principle

Pre-cleaned compressed air from DDp medium coalescer flows outside-in through the filter cartridge:

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

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

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

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

Ultra-dry, trace-low-residual-oil compressed air flows downstream to QD+ activated carbon filter for complete oil vapor adsorption treatment.
