Pressure regulator and oiler in one. In order to use compressed air sanding tools, e.g. LEX 3 150, a specific pressure and a specific amount of oil is required. The VE-CT service unit is perfect for combining this in a mobile system. The service unit mixes air with small amounts of oil. This lubricates components, such as the discs in compressed air sanders, and gives connected compressed air tools a longer service life.
