Abstract
The present invention relates to an air-valve unit for a vacuum system. The valve unit may include a control part, which detects a pressure of an external exhaust space to output an on/off signal, to actively control supply/blocking of air into/from an exhaust hole. Also, the valve unit is preferably constituted by a plurality of holes and electronic valves so that an opening/closing of an outlet of each of the holes is controlled by the control part, and thus, extension of a vacuum generation line or combination of generation/destruction lines may be implemented.
