An exhauster baffle is provided that may be used to prohibit fluid flow through a cavity except when a pressure on one side of the exhauster baffle is greater than a pressure on another side of the exhauster baffle. The exhauster baffle includes a body portion defining an opening, a sealer disposed on the body portion, and a flap disposed over the opening for regulating fluid flow through the opening. In one embodiment, the flap exposes the opening of the body portion to allow fluid to flow through the cavity when the pressure on one side of the exhauster baffle greater than the pressure on another side of the baffle to equalize pressure.
