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 check valves. The addition of check valves is ideal for low-flow and intermittent operations in high humidity conditions.

Feature

Check Valves

The Extreme Humidity Desiccant Breathers, equipped with check valves, provides equipment protection in wash down areas, a common challenge in many industrial environments. These check valves also isolate equipment from the ambient conditions, particularly in high moisture areas. By creating a barrier against external humidity, they play a pivotal role in extending the lifespan of the equipment.

Feature

Tri-Fit Connection

Desiccant Breather has a versatile multi-fit connection, making them adaptable for various industrial applications. This unique connection feature allows the breathers to easily thread into different types of threads, including MNPT, BSPT, and BSPP, providing a broad compatibility range. To further enhance the effectiveness of the connection, each breather is equipped with an O-ring. This addition ensures a secure, leak-proof seal.

Special Feature

Desiccant Color Options

You have a choice between blue and orange desiccant breathers to meet the diverse moisture control needs of your industrial equipment. 

Feature

Installation Date Label

An Installation Date label is included with each desiccant breathers. By recording the installation date, you can gain valuable insights into the efficiency and longevity of the breather across various operational environments. This tracking is instrumental in evaluating the breather's effectiveness, allowing for data-driven decisions regarding future purchases or upgrades, tailored to your specific conditions. Additionally, understanding the service duration of the breathers facilitates effective budgeting for replacements and efficient inventory management. This proactive approach not only helps in avoiding premature replacements but also ensures that you are making the most cost-effective use of your desiccant breathers.

Additional Features

Water Vapor Adsorbent
The silica gel used in the Watchdog Extreme Humidity Breathers adsorbs up to 40% of its own weight.
Visual Indication
When maximum adsorption is reached, the silica gel changes color, indicating replacement is needed.
Center Tube
The center tube is made from durable nylon material, which gives the element rigidity and ensures uniform airflow through the silica gel.
Durable Construction
Watchdog Extreme Humidity Desiccant Breathers are manufactured from rugged ABS plastic.
Dual Filtration System
A dual layer of filter media is located at the top of the silica gel bed. This serves a dual purpose: it effectively prevents the migration of silica dust while also capturing oil mist. Additionally, it ensures even distribution of air across the filter media and the silica gel.
