<p>A ventilation system (400) includes a ventilation tile (100, 100'). The ventilation tile (100, 100') has a substantially circular opening (106) to allow air to flow through the ventilation tile (100, 200) and a collapsible damper (102, 408) operable to collapse and expand to alter the size of the substantially circular opening (106) in the ventilation tile (100, 100') and thereby variably restrict air flow through the substantially circular opening (106).</p> |
