When a reservoir or gearbox breathes, air containing moisture is ingested into the system. Temperature fluctuations will cause this moisture to condense which can speed up the oxidation of the fluid and lead to damage in the system.

Using SVDB series Desiccant Breathers, the incoming air first passes through a coarse filter, then a Drying Agent and finally an PU washer to filter out rough dirt particles.

Type Description

The SVDB series from STAUFF is a simplified design for less demanding applications. In contrast to the SDB and SDBL series, Desiccant Breathers of the SVDB series must be replaced when the service life of the Complete Unit is reached.

The UV-resistant one piece plastic housing is designed with a female BSP thread on the bottom. The Particle and Silica Gel Breather can be installed with a adaptor. A change in the color of the desiccant material indicates that it needs to be replaced (from red to orange in the standard version). Saturated Drying Agent is not replaceable, so that the entire unit is disposed of when it reaches the end of its service life.
