Key Product Features

Frontline Full System Protection

Serves as the first barrier of compressed air purification system, intercepting pipeline rust, scale, industrial dust, massive condensed water and large oil droplets. It significantly reduces pollutant load on downstream medium coalescing, ultra-precision and activated carbon filter elements, extends their service life, and prevents premature saturation of refrigerated dryer desiccant.

Low Pressure Drop Energy-Saving Design

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

Large Dirt & Liquid Holding Capacity

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

Double 304 Stainless Steel Perforated Support Cage

Inner and outer metal mesh resists high-speed airflow impact, prevents filter media collapse, deformation and fiber shedding, eliminating secondary fiber contamination of clean compressed air.

Working Principle

Raw unpurified compressed air flows into the cartridge from the outer mesh layer. 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 via gravity. Primarily purified compressed air flows into secondary medium coalescing filter for further deep oil removal.

Application & Industries

Serves as the first-stage coarse protective filter in compressed air purification systems, installed upstream of medium coalescing filters and refrigerated air dryers.

Widely used in heavy machinery processing, automotive manufacturing, packaging printing, textile factories, general spray painting, large pneumatic tool stations, food primary processing, medium & large laser cutting and factory centralized high-flow compressed air supply systems.
