Whats is a Des-Case Desiccant Breather?

Read our previous blog on this but a Des-Case Desiccant Breather is a vital step in oil contamination control and the first line of defence against lubricant contamination. Studies have shown 50-70% of lubricant contamination can come from outside the equipment.

Des-Case Breathers

Des-Case's breathers are designed to replace traditional dust caps on equipment and reservoirs. These breathers utilize desiccant technology to absorb moisture and a multi-layered filter to capture particles, preventing them from entering the system. This helps in maintaining fluid cleanliness and extending the life of the lubricant.
