Abstract
A ventilation system includes a ventilation tile. The ventilation tile has a substantially circular opening to allow air to flow through the ventilation tile and a collapsible damper operable to collapse and expand to alter the size of the substantially circular opening in the ventilation tile and thereby variably restrict air flow through the substantially circular opening.
