Desiccant breathers are a proven method of removing water contamination from lubricating fluids. This is done through the use of silica-gel technology. The air is drawn through a silica-gel bed which extracts the water vapor from the air. Trico’s Watchdog breathers use a color changing technology to be a visual indicator of maximum adsorption, changing from gold to dark green letting you know its time to quickly change your desiccant breather.
