Abstract
In an exhaust assembly, each particular louver of a plurality of louvers may be hingedly coupled to a generally circular bracket and may be arranged with respect to the air mover and each other such that in the presence of airflow generated by the air mover, the plurality of louvers rotate to an open position relative to the generally circular bracket under force of the airflow such that airflow passes freely through the exhaust assembly and in the absence of air flow generated by the air mover, at least one of the plurality of louvers rotates to a closed position relative to the generally circular bracket under force of gravity and mechanically interacts with a remainder of the plurality of louvers such that all of the plurality of louvers rotate to the closed position such that flow of air through the exhaust assembly is blocked by the plurality of louvers.
