Use Des-Case desiccant breather to protect your lubricants

What is a Desiccant Breather?

The desiccant breather replaces the standard dust cap or OEM breather cap on equipment, offering better filtration to protect against even the smallest particulates that destroy the effectiveness of your machinery, and cause downtime and costly repairs. As air is drawn into equipment through the breather, the layered desiccant 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.

Breather Benefits

Every Des-Case breather has been designed to work in a wide variety of industries and applications, using quality, rugged materials and innovative designs in technology. We’re so confident you’ll love the results you see when using our breathers that we’ll even send you one to try completely free. With the most durable polycarbonate casing in the industry, an impact-resistant standpipe that creates optimal and even airflow, quality check-valve technology, honeycomb oil-reducing technology, and so much more. Des-Case has the right solution for virtually any environment or application.
