ABSTRACT:
A central vacuum system for workspaces such as auto body or wood shops. A vacuum generating unit is rotatably mounted at a level above the heads of the shop workers and integrated with a rigid boom having a flexible vacuum hose at its distal end such that the boom may be swung in an arc parallel to the floor space and thereby give access to the vacuum over a wide area. In a preferred embodiment, the boom is hinged at its center so as to facilitate access to the vacuum within the radius of the arc.
