Watchdog Breather Adapters

Watchdog Breather Adapters

Watchdog Desiccant Breathers are easily installed using one of several adapters designed for different applications.

The Bypass Adapter (39207) is designed for applications where there is very heavy oil mist being expelled from the equipment. When air is breathed into the equipment, it passes through the Watchdog® and is cleaned and dried. When the air is breathed out of the equipment it enters the adapter and is expelled to the outside without passing back through the breather. This protects the breather from oil contamination.


The Watchdog Breather Adapters are used with the Watchdog Desiccant Breathers and Watchdog EX Series Breathers products that are used to prevent the entry of moisture and particulate contamination into industrial equipment. The Watchdog Breather Adapters are used to quickly and easily install the Watchdog Breather family to different types of applications.
