Key Product Advantages

First-stage primary protection, greatly extend service life of downstream A/HE/C precision filters

Installed at the front of the whole air treatment system, this P-grade prefilter intercepts massive pipeline rust, welding dust, sand scale and bulk free water. It avoids rapid blockage of medium, ultrafine and carbon filters caused by large particulate impurities, effectively reducing overall spare parts consumption.

Ultra-large dirt holding capacity for heavy dust industrial environments

Thick multi-layer polyester fiber matrix stores massive solid dust and condensed water within medium size. Outer thick white foam accelerates large water droplet backflow, slows pressure rise in dusty workshops and reduces frequent maintenance downtime.

Anti-clogging thick fiber media, long service life for harsh working conditions

High-density gradient polyester fiber has strong anti-blocking performance, not easy to be penetrated by large dust particles, effectively preventing downstream pipeline secondary pollution from solid debris.

Low initial differential pressure reduces medium compressor power loss

Loose gradient pore structure ensures small airflow resistance under full rated flow, stable low backpressure reduces continuous load of medium screw compressors and cuts factory electricity costs.

Working Principle

Raw compressed air flows through the cartridge outside-in:

Large solid dust, rust scale and bulk water droplets are intercepted by outer thick white foam and outer fiber layer, drain to filter bowl by gravity.

Fine residual tiny particles are trapped by multi-layer gradient polyester fiber media.

Primary pre-cleaned air flows downstream to medium coalescing filter for further oil-water separation.

Application Industries

General metal processing workshops, medium automotive component production lines, small & medium paint booth front protection, plastic injection molding factory air supply, mining auxiliary pneumatic equipment, mechanical welding workshops, medium electronic assembly factory central air source.
