Key Product Advantages

First-stage protection for all precision downstream filters to cut overall consumable cost

As the front pretreatment stage of the entire purification system, it intercepts most coarse dust and rust contaminants, drastically reducing solid contamination load on DD/QD and activated carbon cartridges, extending service life of high-cost precision filters and lowering overall factory maintenance expenditure.

Ultra-large dust holding capacity for heavy-dust industrial workshops

Deep-pleated gradient glass fiber matrix provides massive dust storage volume, resisting rapid clogging in machining, forging, sandblasting and other dusty environments, minimizing production downtime caused by frequent filter replacement.

Ultra-low airflow resistance to reduce long-term power consumption of air compressors

Large-area deep-fold filter media optimizes internal air channels, maintaining stable low pressure drop under 24/7 full-load continuous operation, effectively cutting extra power consumption of air compressor units and electricity costs.

Hydrolysis & abrasion resistant media without fiber shedding

Hydrolysis-proof borosilicate glass fiber matched with stainless steel support cage prevents fiber shedding under long-term humid compressed air impact, 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 thick white non-woven fabric to trap large coarse solid particles;

All solid particles larger than 3μm are captured and stored inside gradient glass fiber media;

Application Industries

General metal machining workshops, metal forging plants, sandblasting workshops, textile printing factories, packaging printing equipment, auto repair spray booths, medium factory centralized air compressor stations, construction machinery air supply systems, ordinary full-automatic pneumatic automation production lines, low-demand food packaging equipment.
