Key Product Features

Low Differential Pressure & Energy Saving

Deep-pleated glass fiber media expands effective filtration area to the maximum. Smooth internal flow channels reduce air turbulence, maintaining stable low pressure loss under 24/7 full-load continuous operation. It cuts extra power consumption of air compressors and lowers overall factory air supply operating costs.

Ultra-Large Dirt & Liquid Holding Capacity

Multi-gradient depth filtration matrix stores large volume of separated lubricant oil, condensed water and solid sludge. Maintenance intervals are significantly prolonged to minimize production downtime caused by filter replacement.

Heavy-Duty Stainless Steel Reinforced Support Cage

Dual stainless steel mesh cages withstand strong high-speed airflow impact under heavy industrial conditions. It prevents media collapse, deformation and fiber shedding to avoid secondary contamination of clean compressed air.

Working Principle

Raw unprocessed compressed air flows into the cartridge through the outer stainless steel protective mesh. The outer coarse fiber layer traps large solid particles, liquid water and bulky oil droplets. Coarse oil mist coalesces into heavy liquid condensate, which sinks to the filter housing bottom and drains automatically via the drain port. Pre-cleaned compressed air flows forward to the H-grade superfine coalescing filter for further trace oil mist treatment.

Application & Industries

Primary protective pre-filter for medium & large flow industrial compressed air post-processing systems, installed upstream of superfine coalescing filters and refrigerated air dryers.

Widely used in heavy machinery manufacturing, automotive production lines, packaging & printing industrial parks, textile factories, industrial spray coating, large pneumatic tool stations, food primary processing, medium & heavy laser cutting, and factory centralized compressed air supply stations.
