Key Product Advantages

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

As the front-line pretreatment element of the entire compressed air purification system, this PDp white mesh filter intercepts most coarse solid impurities, pipeline rust and scale. It drastically reduces solid particle contamination load on DDp, QDp coalescing and activated carbon cartridges, effectively lowering replacement frequency and overall system maintenance costs.

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

Thick deep-pleated gradient glass fiber matrix provides massive dust storage volume, resisting rapid clogging in metal machining, forging and dusty production workshops, avoiding unplanned production downtime caused by frequent filter changes.

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, reducing extra power consumption of medium air compressor stations and cutting long-term electricity expenditure.

Hydrolysis & Abrasion Resistant Fiber-Free Construction

Hydrolysis-proof borosilicate glass fiber matched with stainless steel support cage eliminates fiber shedding under long-term humid compressed air impact, preventing 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 non-woven fleece to intercept large coarse solid particles;

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

Application Industries

General metal machining workshops, metal forging plants, 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.
