Watchdog Desiccant Breathers

Watchdog® Desiccant Breathers are a unique particle filtration and water-removal system. They prevent destructive contaminants from entering industrial equipment as air is breathed in and out due to thermal expansion or fluid level changes. By allowing only clean, dry air into industrial equipment, the Watchdog Desiccant Breathers prolong fluid life, reduce abrasive wear, and decrease downtime and repair costs.

Feature

Optimal Airflow and Protection with Air Intakes

Desiccant breathers are equipped with air intakes located at the bottom, which are initially sealed with a label to ensure moisture protection during transit and storage. Once in use, these intakes are designed to be open, allowing for optimal airflow that is essential for the efficient functioning of your equipment. This design ensures that the breathers are both preserved before installation and fully functional during operation.

Feature

Tri-Fit Connection

The Desiccant Breathers have 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 Desiccant 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 Desiccant Breathers are manufactured from rugged ABS plastic.
Dual Filtration System
A dual layer of filter media is located at the top and bottom 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.
