Key Product Features

Frontline Full System Protection

As the first-stage barrier of compressed air purification system, it intercepts pipeline rust, scale, industrial dust, massive condensed water and bulky oil droplets. It drastically reduces pollutant load on downstream medium coalescing, superfine and activated carbon filter elements, extends their service lifespan and prevents premature saturation of dryer desiccant.

Low Pressure Drop Energy-saving Design

Optimized deep-pleated glass fiber media expands effective filtration area remarkably. It maintains stable low airflow resistance under long-term 24-hour full-load continuous operation, cuts extra power consumption of air compressors and lowers overall factory air supply operation costs.

Extra Large Dirt & Liquid Holding Capacity

Multi-gradient layered depth filtration structure stores massive separated water, lubricating oil and solid contaminants, prolongs maintenance intervals and minimizes production downtime for filter replacement.

Reinforced Plastic Anti-breakage Support Cage

Inner and outer plastic frames withstand high-speed airflow impact, prevent filter media collapse, deformation and fiber shedding, and eliminate secondary fiber contamination of clean compressed air.

Working Principle

Raw unpurified compressed air flows into the cartridge from the outer plastic protective frame. The outer coarse fiber layer captures large solid particles, liquid water and bulky oil droplets; minor oil mist is pre-coalesced into heavy liquid droplets that sink to the housing bottom drain port and discharge automatically by gravity. Primarily purified compressed air flows into the secondary medium coalescing filter for further deep oil removal.
