Filtration precision: 10um, β10 (c) >400;

Operating temperature: —5°F ~250°F;
Filtration efficiency: >99.5%;

Filter crushing pressure: 20 Bar;

Suitable for Hydraulic pump stations produced by Eaton, Parker, Internormen
and others.


Wind Turbine Desiccant breathers (Air Filter)

Wind turbine Desiccant breathers (Air filter) are a key component designed to protect lubricant quality,
widely used in gearboxes, storage tanks, transformers, hydraulic stations and
other pieces of equipment. Due to thermal expansion and contraction of the
fluids in these pieces of equipment, and the inability to truly seal these
components, there must be a breather port to allow air to pass freely. Our

desiccant breathers not only filter solid contaminants from the air entering your sensitive equipment, but they also remove moisture from the entering air to keep your oil clean and dry. 

Desiccant filtration products

Efficient water vapor absorption.
Simple and reliable lubricant protection device.
Flexible polycarbonate plastic shell with elastic, shock—resistant structure.
Two—way controllable airflow.
Multi-stage filtration process.
Color-Changing desiccant gives visual replacement indication.

Gearbox filter - offline
