Please Note : This is intended as a general road map for sizing only ; other considerations, such as : humidity level, frequency of air flow, ambient temperatures, and chemical compatibility are very important in sizing a snorkel by rights. Larger applications and special circumstances typically require the most thorough analysis. Please contact Des-Case for aid in sizing a snorkel.

APPLICATIONS

  • Totes
  • Transformers
  • Storage Tanks
  • Hydraulics

How It Works

The desiccant snorkel replaces the standard dust cap or OEM snorkel cap on equipment. As vent is drawn into equipment through the snorkel, the layer 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.
