Des-Case Non-Desiccant Breathers
The Des-Case Non-Desiccant Breather is an excellent choice for low-humidity environments where the primary concern is elimination of contamination ingress. Additionally, these units are suitable for applications with water-based fluids, such as water glycol hydraulic fluid.
The Non-Desiccant breather keeps the reservoir isolated from free water as well as particles down to one micron.

Please Note: The above sizing table is only a general guideline. Many other factors such as humidity level, the frequency of airflow, ambient temperatures and chemical compatibility must be considered to determine the size of a breather accurately. Larger applications, as well as special or unusual circumstances, will in many cases require a thorough analysis. Please contact RO-QUIP for help in determining the proper size a breather.
Applications
- Low Humidity
- Oil Misting
- Arid Environments
- High Dust
- Water-Based Fluids
- Oil Sight Glasses (DC-ND-2)
- Small Gearboxes (DC-ND-2)
The hydrophobic media bars water from entering when air flows through the breather, whereas the pleated particulate filter retains dirt, so both elements are prevented access to the equipment.
