Key Product Advantages

Ultra-high 0.01μm submicron coalescing performance

Captures invisible micro oil mist and fine dust, delivers ultra-clean compressed air for high-standard production processes.

Folded deep media with large dirt holding capacity

Extended folded area stores massive oil sludge and dust, slow differential pressure rise during service life, effectively reducing compressor energy consumption.

Dual-end integrated sealing structure, zero air bypass leakage

One-piece molded end caps with embedded gaskets eliminate short-circuit airflow, stable long-term filtration effect.

Working Principle

Pre-filtered compressed air flows from outside to inside through gradient glass fiber media.

Coarse liquid droplets and large particles are trapped by outer pre-layer and drain downwards to filter bowl.

0.01μm ultra-fine oil mist collides with glass fiber media, coalesces into large liquid oil droplets and flows down for drainage.

Ultra-clean compressed air with residual oil ≤0.01ppm flows out to downstream equipment or C-grade activated carbon filter.

Filter media cannot be cleaned or regenerated; once saturated by oil contaminants, full replacement is required.

Application Scope

Automotive electrostatic painting workshops, precision electronic component assembly, laser cutting & laser marking machines, pharmaceutical sterile production, food sterile packaging, laboratory gas supply, printing industry.
