Key Product Advantages

Primary Barrier to Extend Service Life of Downstream High-Cost Filter Cartridges

As the first stage of the full compressed air filtration system, this PD prefilter intercepts most coarse rust, scale and solid impurities in advance. It drastically reduces contamination load on DD general coalescing, PD high-efficiency coalescing and QD activated carbon elements, lowering overall maintenance frequency and spare parts procurement costs for central air compressor stations.

Extra-Large Dust Holding Capacity for Heavy-Dust Industrial Environments

Thick multi-gradient glass fiber matrix provides massive dust storage volume, resisting rapid clogging in machining, forging, mining and other dusty workshop conditions, effectively extending replacement maintenance cycles and reducing production downtime.

Low Airflow Resistance for Energy Saving

Large-area deep-pleated filter media optimizes internal airflow channels, maintaining stable low pressure drop under 24/7 full-load continuous operation, reducing extra operating load of air compressor units and cutting long-term electricity expenses.

Hydrolysis & Oil Resistant Composite Prevents Secondary Pipeline Contamination

Hydrolysis-proof, oleophobic glass fiber paired with stainless steel support mesh avoids fiber shedding, eliminating secondary pollution 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 the outer non-woven fabric buffer layer;

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

Dust-free pre-cleaned compressed air flows downstream to DD coalescing filter for liquid oil and water separation treatment.

Application Industries

Large machining workshops, forging plants, textile integrated factories, packaging printing workshops, general automotive repair spray booths, group factory central air compressor stations, construction machinery air supply systems, full-automatic ordinary pneumatic production lines.
