Non-Desiccants

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.

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.

APPLICATIONS

  • Low Humidity
  • Oil Misting
  • Arid Environments
  • High Dust
  • Water-Based Fluids
  • Oil Sight Glasses (DC-ND-2)
  • Small Gearboxes (DC-ND-2)

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.
