Coalescing Filters

Part No: HFN135Q

Filtration Accuracy: 3μm, Filtration Efficiency: 92%

Function: Remove large‑size dust, rust particles and bulk liquid water. Not for oil mist or oil vapour removal.

Max Working Pressure: 16bar

Working Temperature: ‑10℃ ~ +65℃

Dimension: Φ110×510mm

Service Life: 5000‑8000h; replace when pressure drop reaches 0.35bar; standard service interval 8000 hours or 1 year

Filter Media: Gradient glass‑fiber coarse filter media with primary hydrophobic drainage layer

Main Features

HFN135Q coarse pre‑filter acts as the first‑stage filter of air compressor system. It intercepts large solid contaminants, pipeline rust and bulk liquid condensate, protecting downstream coalescing filters and air dryers, complies with ISO8573‑1 compressed‑air quality standard.

Primary hydrophobic fiber layer enables fast separation and drainage of large liquid droplets, reducing liquid carry‑over to downstream precision elements.

Gradient multi‑layer coarse media provides high dirt‑holding capacity, anti‑fiber shedding and low pressure‑drop under high‑flow conditions.

This pre‑filter cannot achieve high‑purity air quality when used alone.

Applied for main‑line pre‑treatment, protecting refrigerated dryers, desiccant dryers and subsequent precision filter elements.

Application Industries

Compressed‑air pre‑treatment, general factory air supply, main‑line primary filtration, pre‑protection for air drying equipment, mechanical‑equipment air‑source pre‑processing

Product Summary

With 3μm filtration rating, it fits HFN135 filter housing and captures large dust particles and bulk liquid droplets for upstream system protection. Not for standalone high‑precision filtration.
