ABSTRACT:
A vacuum system for multiple work areas preferably includes a vacuum source connected to a plurality of vacuum conduits leading to the work areas. Each of the conduits has a vacuum opening in the vicinity of the associated work area, through which gases and other airborne contaminants generated by equipment in the work area are drawn into the vacuum conduit, and thereby removed from the work area. Valve members are associated with each of the vacuum conduits, and are positionable in the conduits so as to prevent air flow through the conduits. Structure is provided to open the valve whenever the associated equipment is in the contaminant-generating mode of operation, and to close the valve whenever the equipment is not in this mode of operation.
