Non Desiccant Breathers

Des-Case Non-Desiccant breathers prevent contamination ingress in low humidity environments or in applications where water-based fluids are in use (e.g. water glycol hydraulic fluid). They help to prevent contamination by preventing free water as well as particles down to 1 micron from getting into the reservoir.

Non Desiccant Breather Cut Thru

HOW IT WORKS

As wet, contaminated air is drawn through the unit, the hydrophobic media repels water while the pleated particulate filter captures dirt, preventing both from entering the equipment.

Please Note: This is intended as a general guideline for sizing only; other considerations, such as: humidity level, frequency of air flow, ambient temperatures, and chemical compatibility are very important in sizing a breather properly. Larger applications and special circumstances typically require the most thorough analysis. Please contact Des-Case for assistance in sizing a breather.
