Obviously, your business does not involve using your compressed air to spray paints, or you would know of problems a little water can cause.  But water’s rap sheet is long and varied and is not limited to crimes against paint jobs.  Water in your compressed air will flush away lubricants in your air tools and air powered machines, increasing wear and causing premature breakdowns.  Also, it can mix with soluble and corrosive solder fluxes in your compressed air piping system and corrode machines and tools downstream.  Water is also corrosive when mixed with compressor oil mist.  Fortunately, water is easy to outsmart.  Appropriately sized refrigerated or desiccant air dryers effectively remove all the moisture from your compressed air.  Add particulate and coalescing filters to remove particulate and oil contamination, and your compressed air will be clean, dry, and ready to effectively perform the work you prescribe for it.  However, as with your compressor, the appropriate size and type of dryer are critical.  You should request that a professional air compressor service company, such as Air Compressor Service, look at your operation and recommend the appropriate equipment.
