The perfect solution for high humidity and high dust environments.
In certain extreme operating environments such as paper mills or a steam cleaning rooms, the humidity level far exceeds normal industrial environments. In these situations, lubricants and other fluids stored in tanks and reservoirs need the protection of a desiccant breather even more. However, small temperature variations draw in the humid air and unnecessarily reduce the life of the breather. The Watchdog® Extreme Humidity Breathers incorporate two check valves, one to control airflow into the protected reservoir, and one to control airflow out. The check valves provide a closed system until airflow is required, extending the service life of the desiccant. Specifically, the intake check valve allows airflow into the breather only when differential pressure between the atmosphere and fluid reservoir exceeds a 0.1 psi threshold, while the exhaust check valve permits air to exit the reservoir when the differential pressure exceeds a 2.0 psi threshold. A 0.1 psi check valve is also available for exhaust. The end result is longer desiccant life by allowing the air to flow through the breather only when needed to protect the integrity of the tank.
Unlike a membrane system, which does not allow internally generated gases and contaminants to exit the system, the Watchdog® Extreme Humidity Breather offers all of the advantages of breathing air in and out of the tank while removing water vapor and solid particles before they contaminate the fluid.
