Vacuum Generators with  different built-in combinations of Filter, Valves and  Switches are available. These are the VK Type offering a total of 18 combinations, see below. Each combination can be use as it is, a stand-alone unit, or as a  manifold unit, in which case a manifold has to be ordered separately. The stand-alone unit comes in 2 selections, either with vacuum and pressure ports on one side, or on opposite sides.
