Desiccant air breather

Introduction
Standard breathers provide simple, yet dependable protection from moisture
and particulate contamination in lubricants and equipment across multiple
industries and applications. These versatile breathers are five times
more effective than the leading non-desiccant breathers,
providing optimal defense against humidity for your applications.

Application
Application Totes/transformer/storage tanks/hydraulics
Operation The desiccant breather replaces the standard dust cap or OEM breather cap on equipment. As air is drawn into equipment through the breather, the layered filter elements remove particulate while the desiccant beads strip harmful moisture. While in service or during shut-down, the desiccant beads attract moisture from inside the equipment reservoir, actively drying the equipment.
Principle Removes moisture in the headspace of equipment
Eliminates rust-forming condensation
Prevents sludge deposits and water-contaminated oil
Prevents contamination ingress
Provides longer lubricant life
Reduces wear and tear on equipment, prolongs life
