<p>The framework comprises connected vertical and horizontal, hollow, tubular, structural, frame members for housing the machine. The frame members are separate and enclosed with respect to the housed machine and support the machine as one use and serve as a conduit for exhaustion of contaminants e.g. dirt, ozone and heat from the machine as another use. Air inlets (15) are positioned within the frame members (20,22), chambers being placed at each junction of the frame members to improve air flow efficiency. A negative pressure source i.e. blower (40) is connected to the frame members for creating a vacuum pressure within the frame members in order to draw contaminants from the environment of the machine. A filter (30) is positioned between the blower and a tubular member e.g. base of the frame.</p> |
