Abstract
Abstract An apparatus for use with a multi-station workspacae including a predetermined number of core walls which define an enclosed core. The core walls include an inlet at or below a predetermined height. The apparatus includes a platform positioned in the core at a location above the predetermined height substantially separating the core into a lower air intake chamber and an upper air discharge chamber. The platform further includes a filter in the lower chamber and a blowers drawing air from the intake chamber through the filter to the upper chamber. Finally, a core lid is positioned at the top of the core and includes air discharge vents. The discharge vents include a top grid for discharging air in a vertically upward direction and side vents proximate each of the core walls for discharging air in a substantially horizontal direction out from each of the core walls.
