Air circulation system

Abstract

An apparatus for use with a multi-station workspace 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 are side vents proximate each of the core walls for discharging air in a substantially horizontal direction out from each of the core walls to form an envelope of clean, filtered air for the workspace.
