Watchdog Extreme Humidity Desiccant Breathers
In environments with extreme humidity, the lubricants and other fluids stored in various equipment need desiccant breathers to remove water vapor and solid particles. However, small temperature variants can draw in humid air and unnecessarily reduce the life of the breather. The Watchdog® Extreme Humidity Breathers incorporate two check valves. One valve controls airflow into the protected equipment, and the other controls airflow out. Together, they allow air to flow through the breather only when necessary, prolonging the life of the desiccant.
Feature
Reusable Top Cap
The top cap allows for the economic replacement of the desiccant cartridge. When maximum adsorption is reached, the silica gel turns from orange to dark green, indicating replacement is needed. The silica gel used is chemically inert, non-corrosive, and does not contain cobalt chloride, a heavy metal. The color-changing dye used is environmentally safe and meets all health and safety requirements.
Additional Features
- Water Vapor Adsorbent
- The silica gel used in the Watchdog Extreme Humidity Breathers adsorbs up to 40% of its own weight.
- Durable Construction
- Watchdog Extreme Humidity Breathers are manufactured from rugged ABS plastic and impact modified acrylic.
- Easy Connection
- Models are available with 1" slip fit connection which mates with the standard Watchdog Desiccant Breather Adapters or with a 2" NPT male connection.
