Desiccant breathers are mounted at tanks of hydraulic and lubrication systems in order to prevent humidity from entering the systems during ventilation.
General
Water in hydraulic and lubrication oils may have the following causes:
› Environment humidity
› Spray-water
Already small quantities of free water in oil can lead to acidifi cation. Corrosion of surfaces can be the result. Due to water the oil characteristics change, e.g. decreased load-carrying capacity, reduced temperature resistance. In order to avoid economic damage, the oil must be protected against water.
Special features
Desiccant breathers prevent solid particles as well as humidity, snow, spray- or rainwater from entering. They may even be used in sea atmosphere without any problems. The fi lter consists of a vessel with silica gel and an integrated ventilating fi lter.
Performance features
› Water abstraction from the humid air to maintain the lubrication effect and to prevent oxidation
› Color change when the maximum dirt holding capacity of the fi lter element is reached
Maintenance
With color change of the silica gel from red to orange or with clogged fi lter element.
Accessories
Additional humidity sensors for monitoring of the pressure fl uid are available on request - LubCos humidity sensors dimensions and technical data see data sheet LubCos H2O and LubCos H2O+ II.
Operation
The air fl ows via the in the bottom integrated valves into the desiccant breather, therein the humid air is fi rst dried in Silica gel, then the solid particle contamination is removed by the 3 µm fi ne ventilating fi lter.
