Moisture can also lead to unfavourable reactions with the fluid and cause corrosion in the hydraulic reservoir and in the lines. To prevent both these issues, it is practical to in- stall a desiccant air breather on the hydraulic reservoir. In the revised portfolio, Stauff took into account the different areas of application and ambient conditions. 7 0 to 80 per cent of all machine failures are caused by contaminated hydraulic oil.

To prevent both these issues, it is practical to install a desiccant air breather on the hydraulic reservoir. In the revised portfolio, Stauff took into account the different areas of application and ambient conditions. Hydraulic systems “breathe”. The level of the hy- draulic oil in the reservoir rises and falls during operation. To avoid overpressure or underpressure in the closed circuit, air has to be able to escape through an opening and flow back in again. This process, however, can allow moisture and dirt to enter into the system. Desiccant air breathers installed on the reservoir opening have two functions: They filter out contamination and absorb moisture. What does a desiccant air breather have to do? There are different requirements for desiccant air breathers depending on the area of application and the ambient conditions. In mobile work machines, they have to be particularly robust and vibration-resistant. While things are a bit calmer in stationary systems, there is often less space available, so that the protection for the hydraulic reservoir cannot take up too much room. In other cases, it might be crucial that a particularly cost- effective desiccant air breather can be easily replaced by untrained personnel in a few simple steps. For these different requirements, the Stauff hydraulic accessories offer three series, each in turn with many different vari- ants and specifications. Each desiccant air breather is an assembly that con- tains filter elements and drying materials for filtering out dirt particles and binding the moisture in the air. The As a part of hy- draulic units, giant and desiccant air breathers from Stauff are used in a number of applications in mobile and industrial hydraulics. Images: Stauff
