What Are Desiccant Breathers?

Desiccant breathers are filtration devices installed on hydraulic reservoirs, storage tanks, gearboxes, transformers, and industrial fluid containers. Their primary purpose is to remove moisture and airborne contaminants from the air entering the equipment.

Hydraulic reservoirs naturally breathe during operation because fluid levels rise and fall with temperature and system movement. As outside air enters the reservoir, it may carry humidity, dust, dirt, and microscopic particles. Without proper filtration, these contaminants enter the hydraulic oil and cause system damage over time.

A desiccant breather contains:

  • Moisture-absorbing desiccant material
  • High-efficiency particulate filters
  • Durable housing for industrial environments

These components work together to keep hydraulic systems clean, dry, and protected.
