Key Product Features

Front-stage comprehensive protection

Captures pipeline rust, scale, dust, condensed water and bulk oil droplets, effectively protects downstream ultra-precision coalescing filter and activated carbon filter, extends their service cycle and avoids dryer adsorbent contamination.

Low differential pressure energy-saving design

Uniform folded gradient filter media provides large effective filtration area, maintains stable low airflow resistance during long-term full-load operation and cuts compressor power consumption.

Hydrophobic & oleophobic surface coating

Speeds up separation and drainage of liquid oil and water, prevents premature clogging, and greatly improves dirt & liquid holding capacity to reduce maintenance frequency.

Reinforced perforated inner support cage

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

Working Principle

Unpurified compressed air flows from outside to inside through multi-layer glass fiber media. Large liquid water and oil droplets are intercepted by the outer coarse fiber layer; tiny 0.1μm oil mist aerosol is captured and coalesced into large liquid droplets, which flow down to the filter housing drain port for automatic discharge, and relatively clean compressed air flows out to the next-stage purification equipment.

Application & Industries

Used as the core medium coalescing pre-filter in compressed air staged purification systems, installed between coarse filter and ultra-precision filter / refrigerated air dryer.

Widely applied in machinery processing, packaging, textile, general spraying, pneumatic equipment, food processing, small laser cutting and factory centralized air supply systems.
