Des-Case Non-Desiccant Breathers

Air Breather DC-ND-2

The Des-Case Air Breather DC-ND-2 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.

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.
