The best way to eliminate water from any lubricant application is to stop it from getting into the lubricant supply or into the machinery in the first place. In some cases, this is very challenging, but a common technique for eliminating water infiltration into a lubricant is with desiccant air breathers. A desiccant air breather contains material that absorbs water from ambient air before it enters the machine. Breathers can be attached to fill spouts or open breather ports. Most lubricant reservoirs “breathe out” as well as “breathing in,” so desiccant breathers can also serve to remove water that may have been introduced to oils during production, handling, and/or filling.
