APPLICATIONS
- Totes
- Transformers
- Storage Tanks
- Hydraulics
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.
Seeing Pink?
A pink breather means it has done its job keeping moisture out of your lubricants. Time to replace the breather with a new one.
