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.

Cost savings

It costs ten times as much to remove contamination from equipment than it does to exclude it?

Maintaining clean oil

Maintaining clean oil can extend life as much as 2-5 times.

Oil Contamination

Contamination is the greatest single cause of lubricant malfunction and subsequent exceissive wear of parts?

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.
