Extreme Environment Applications

XR-Series breathers typ XR502


XR-Series breathers were originally engineered for the wind power industry but are designed to perform in any extreme environment where protection from dust, moisture and vibration is critical.

These breathers include a metal reinforced base, available with male NPT threads to adapt to your equipment. The base is designed to handle the rigors of high-vibration applications. 

The top cap uses two check valves to prevent outside moisture and solid contaminants from entering the breather until there is a need for airflow. The modular design allows for economical replacement of the desiccant cartridge.

Case Story

Originally, XR-Series breathers were designed for the rigorous requirements for the windmill industry, but they have proven to be a great solution for many mobile applications where there are high levels of vibration, humidity, and dust. 

XR-Series breathers

A distributor of fuels and lubricants in the Midwestern United States mounted three XR-Series breathers on each reservoir on their mobile lube truck. They found by using this design they were able to virtually eliminate the contamination issues they were having due to solid and liquid contamination of their lubricants.
