Key Product Advantages

First-stage full-system front protection, drastically extend service life of downstream M and A precision filters

Installed at the very front of the air treatment circuit, this P-grade prefilter captures massive pipeline rust, welding dust, sand scale and bulk free condensed water. It prevents rapid clogging of medium coalescing and carbon filters caused by large solid impurities, cutting overall factory spare parts consumption and maintenance frequency by over 50%.

Ultra-large dirt & liquid holding capacity adapts to harsh dusty industrial environments

Thick multi-layer gradient polyester fiber matrix stores massive solid dust and condensed water within compact dimensions. Outer thick white foam accelerates gravity drainage of large water droplets, slowing pressure rise in high-dust workshops and reducing unplanned production downtime from frequent filter replacements.

Anti-clogging gradient fiber media avoids downstream pipeline solid contamination

Loose outer + dense inner gradient fiber structure delivers excellent anti-blocking performance, preventing large dust debris from penetrating into rear air pipelines and scratching precision equipment components.

Ultra-low initial differential pressure reduces power loss of small screw compressors

Open loose pore layout ensures minimal airflow resistance under full rated flow. Stable low backpressure lowers continuous running load of small BOGE screw compressors, cutting long-term workshop electricity operating costs.

Working Principle

Raw unprocessed compressed air flows through the filter cartridge from outside to inside:

Large solid dust particles, rust scale and bulk water droplets are intercepted by outer thick white foam and outer polyester fiber layer, draining into the filter bowl via gravity.

Tiny residual fine particles are trapped layer-by-layer by gradient polyester fiber media.

Primarily pre-cleaned compressed air flows downstream to M-grade medium coalescing filter for secondary oil-water separation.

Application Industries

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