Key Product Advantages

Primary Protective Barrier to Extend Service Life of Downstream High-Cost Precision Filters

As the first stage of the full compressed air purification system, this FD grade red element traps most coarse rust, scale and solid impurities upfront. It drastically reduces solid contamination load on FE, FF coalescing and FG activated carbon cartridges, extends their service life and cuts overall system maintenance and spare parts costs.

Ultra-Large Dust Holding Capacity for Heavy-Dust Workshop Environments

Thick deep-pleated gradient glass fiber matrix provides massive dirt storage volume, resisting rapid clogging in machining, forging, mining and dusty production workshops, effectively reducing unplanned production downtime caused by frequent filter replacement.

Ultra-Low Airflow Resistance for Energy Saving

Large-area deep-fold filter media optimizes internal airflow channels, maintaining stable low pressure drop under 24/7 full-load continuous operation, lowering extra power consumption of large air compressor units and reducing long-term electricity expenditure.

Hydrolysis & Abrasion Resistant Fiber-Free Construction

Hydrolysis-proof borosilicate glass fiber paired with stainless steel support mesh eliminates fiber shedding under long-term humid compressed air operation, avoiding secondary pipeline contamination to downstream coalescing media, precision pneumatic valves and spraying equipment.

Working Principle

Raw unpurified compressed air flows outside-in through the filter cartridge:

Air first passes through outer red non-woven buffer fabric to intercept large coarse solid particles;

All solid particles larger than 1μm are trapped and stored inside gradient glass fiber media;

Application Industries

Large metal machining workshops, heavy metal forging plants, textile printing factories, large packaging printing equipment, medium & large factory centralized air compressor stations, construction machinery air supply systems, ordinary full-automatic pneumatic automation production lines, general food packaging equipment.
