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 SDBL series Particle and Air Conditioner, the incoming air first passes through a coarse filter, then a dryer agent material and finally an Air Breather element to filter out any dirt particles in addition to the moisture.

Compact Design

The SDBL series from STAUFF is a compact and flexible design that are used, for example, in power pack and reservoir manufacturing. 

Available in five different housing lengths between 117,5 mm and 322,5 mm and have a diameter of 70 mm, 99 mm or 129 mm depending on the selected length. 

The UV-resistant one piece plastic housing is designed with a female BSP thread on the bottom. The Particle and Silica Breather can be installed with a adaptor.
