Feature

Bypass Flow Adapter

The Bypass Flow Adapter features a smart airflow design that directs exhaust air out before it reaches the reservoir breather. This innovative design shields the desiccant breather from oil mist and system humidity, significantly extending its lifespan. By reducing exposure to contaminants, the adapter ensures better performance and less frequent desiccant cartridge changes.
 

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

An Installation Date label is included with each desiccant breather. 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

Superior Filtration
Dual zone filtration for high dirt-holding capacity and minimal pressure drop.
Inflow/Outflow Check Valves
Protects silica gel from humid ambient conditions, extending life.
Water Vapor Adsorbent
The silica gel used adsorbs up to 40% of its own weight.
Visual Indication
When maximum adsorption is reached, the silica gel changes color, indicating replacement is needed.
Bypass Flow Adapter
Watchdog Bypass Flow Desiccant Breathers check valvesa are positioned inward to inhale from the atmosphere and they must be used with the Bypass Flow Adapter to exhale air out of the system.

Don't Get Trapped

Caution is advised against the emerging practice of substituting desiccant breathers with traditional air breathers in industries prone to high humidity and temperatures, due to the risk of incurring significant expenses. Desiccant breathers stand out for their exceptional ability to absorb moisture, superior filtration performance, affordability, and versatility. They significantly outperform traditional air vents by efficiently eliminating moisture and particulates, safeguarding equipment from corrosion, and improving system dependability and lifespan.

The Forgotten Ones

Desiccant Breathers have been around in our industries for over twenty years now. Most of the plants that I’ve been to typically have some sort of desiccant breather presence.
