Desiccant Breathers

The first line of defense against contamination

desiccant breathers general des case

Use desiccant breathers instead of a standard dust cap or an OEM breather cap on your equipment to obtain better filtration as protection again small particulates. This will help avoid costly repairs and downtime as well as extend the lifespan of the machinery.

When air flows through a breather before entering the equipment, the layered filters remove particulate, and the desiccant beads absorb harmful moisture. When the machinery is not in operation, e.g. during shut-down, the beads attract moisture from the reservoir, in effect drying out the equipment.

RO-QUIP has many years of experience with the Des-Case product line of desiccant breathers, but we do also supply other brands (see further down).
