Key Product Features

Intermediate Deep Oil Removal & System Protection

After coarse filters intercept large particles and liquid water, this element captures conventional system oil mist and tiny water droplets. It greatly reduces pollutant load on downstream Grade C ultra-precision filters and activated carbon filters, extends service life of high-end filter elements, and prevents desiccant inside air dryers from oil contamination and failure.

Low Pressure Drop Energy-saving Structure

Uniform deep-folded glass fiber media provides large effective filtration area. It maintains stable low airflow resistance under long-term full-load continuous operation, cuts idle power consumption of air compressors and lowers overall plant air supply operation costs.

High Dirt & Oil Holding Capacity

Multi-layer gradient depth filtration structure stores large amounts of separated lubricating oil and dust contaminants, prolongs maintenance intervals and reduces shutdown & replacement frequency.

Perforated Stainless Steel Inner Support Cage

Resists impact of high-velocity airflow, prevents filter media collapse and fiber shedding, and avoids secondary fiber contamination of clean air, suitable for 24-hour continuous industrial operation.

Working Principle

Unpurified compressed air flows into the element from the outer surface. The outer coarse fiber layer intercepts large water droplets and oil droplets; inner micro glass fiber captures 0.1 μm submicron oil mist, which collides and coalesces into large liquid droplets. The liquid droplets sink to the bottom drain port of the filter housing by gravity and are automatically discharged. Oil-removed compressed air flows to downstream ultra-precision filtration equipment for further purification.

Application & Industries

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

Widely used in general machinery processing, packaging & printing, textile industry, conventional spray painting, pneumatic tool stations, primary food processing, small & medium laser cutting and factory centralized air supply systems.
