Air Sentry

Air Sentry Breathers are designed to replace the breather cap or air filter on gear boxes, hydraulic fluid reservoirs, bulk storage tanks, oil drums, oil-filled transformers and other fluid reservoirs. Air Sentry desiccant breathers adsorb water from the air before it enters your fluid system and remove particulate contaminants as small as 2 microns. The silica gel changes color as it becomes depleted, turning from gold to dark green. It’s easy to identify the condition of a breather and quickly replace it, maintaining the cleanliness of the fluid reservoir.
