Air Sentry is a leading developer of desiccant breathers designed to keep particulate and moisture contamination from the headspace of gearboxes, reservoirs, tanks and other lubricant and fuel vessels.

Air sentry desiccant breathers adsorb water from the air before it enters your fluid system and removes particulate contaminants as small as 2 microns.

The silica gel changes colour as it becomes depleted, turning from gold to dark green. Its easy to identify the condition of a breather and quickly replace it, maintaining the cleanliness of the fluid reservoir.
