Key Product Features

Frontline Barrier Protection for Entire Air System

Serves as the first purification stage of the compressed air pipeline system. It intercepts pipeline rust, scale, workshop dust, massive condensate and bulky oil droplets. It drastically reduces contaminant load on downstream medium coalescing, superfine and activated carbon filter cartridges, extends their service cycles and prevents premature saturation of refrigerated dryer desiccant media.

Low Pressure Drop & Energy Saving

Deep-pleated microglass media greatly expands effective filtration area. It maintains stable low airflow resistance under 24-hour full-load continuous operation, cuts extra power consumption of air compressors and lowers overall factory air supply operating costs.

Large Dirt & Liquid Holding Capacity

Multi-gradient layered depth filtration structure stores massive separated lubricating oil, condensed water and solid sludge contaminants, extending maintenance intervals and minimizing production downtime during filter replacement.

Impact-resistant Reinforced Support Frame

Dual anti-corrosion plastic cages withstand high-speed airflow impact, preventing media collapse, deformation and fiber shedding to eliminate secondary fiber contamination of clean compressed air.

Working Principle

Raw unpurified compressed air flows into the cartridge from the outer glass fiber protective layer. The outer coarse fiber traps large solid particles, liquid water and bulky oil droplets. Minor oil mist is coalesced into heavy liquid condensate, which sinks to the filter housing bottom and drains automatically by gravity. Primarily purified compressed air flows to the secondary Grade G medium coalescing filter for further oil removal.

Application & Industries

First-stage protective pre-filter for industrial compressed air post-processing systems, installed upstream of medium coalescing filters and refrigerated air dryers.

Widely applied in general machinery manufacturing, automotive production lines, packaging printing factories, textile industrial parks, conventional industrial spraying, pneumatic tool stations, food primary processing, medium-heavy laser cutting and factory centralized compressed air supply systems.
