Extreme Environment Applications

Typical Applications

  • Windmills and Wind Power
    Generation
  • Mining Equipment
  • Mobile Equipment

Air Sentry® XR-Series breathers, originally conceived for the wind power industry, are designed to perform in any extreme environment where protection from dust, moisture and vibration are critical.

XR-Series 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 rebuildable design allows for economical replacement of the desiccant cartridge.
