Key Product Features

Intermediate Oil Mist Separation & System Protection

After Grade X coarse pre-filter intercepts bulk water, rust and large oil droplets, this element captures mainstream submicron oil mist and tiny residual condensate. It significantly reduces pollutant load on downstream ultra-precision and activated carbon filter elements, extends their service life, and prevents desiccant inside refrigerated air dryers from oil contamination and premature failure.

Low Pressure Drop Energy-saving Design

Optimized deep-pleated glass fiber media maximizes 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, moisture and solid contaminants, prolongs maintenance intervals and minimizes production downtime for filter replacement.

Double Stainless Steel Reinforced Support Cage

Inner and outer metal mesh withstands high-speed airflow impact, prevents filter media collapse, deformation and fiber shedding, and eliminates secondary fiber contamination of clean compressed air for heavy-duty industrial operation.

Working Principle

Raw compressed air flows into the cartridge from the outer protective mesh. The outer coarse fiber layer traps large solid particles and bulk liquid droplets; inner ultra-fine glass fiber captures 0.1μm submicron oil mist particles, which collide and coalesce into large liquid droplets. Liquid condensate sinks to the housing bottom drain port and discharges automatically by gravity. Moderately purified compressed air flows to downstream ultra-precision filtration equipment for further deep cleaning.

Application & Industries

Serves as the core intermediate coalescing filter in large-flow compressed air purification systems, installed between coarse pre-filters and ultra-precision filters / refrigerated air dryers.

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