Key Product Features

First-stage system full protection

Traps pipeline rust, scale, industrial dust, liquid water and large oil mist droplets at the front end. Effectively reduces pollutant load on downstream medium coalescing, high-efficiency and activated carbon filter elements, extends their service cycle and prevents early contamination of dryer adsorbent.

Low differential pressure energy-saving design

Uniform dense pleated gradient filter media expands effective filtration area, maintains stable low airflow resistance under long-term full-load continuous operation, cuts air compressor power consumption and running cost.

Fast liquid separation & anti-clogging coating

Special hydrophobic & oleophobic surface treatment accelerates gravity drainage of separated water and oil, avoids premature filter blockage, and greatly improves dirt & liquid holding capacity to lower maintenance frequency.

Reinforced stainless steel perforated inner support cage

Prevents filter media collapse, deformation and fiber shedding under long-term high-flow humid industrial working conditions, eliminates secondary pollution of clean compressed air.

Working Principle

Unpurified compressed air flows from outside to inside through multi-layer composite glass fiber media. Outer coarse fiber layer intercepts large solid particles, liquid water and big oil droplets; residual tiny oil mist is pre-coalesced into larger liquid droplets, which flow down to the automatic drain port of filter housing and discharge out. Primarily purified compressed air flows into the next-stage coalescing filter for deep secondary purification.

Application & Industries

Serves as the first-stage coarse pre-filter in compressed air staged purification systems, installed upstream of medium coalescing filter and refrigerated air dryer.

Widely applied in general machinery processing, packaging, textile, ordinary spray painting, pneumatic tool stations, food processing workshops, small laser cutting equipment and factory centralized air supply systems.
