Abstract: An airborne particle collection system includes an airflow directing unit, register units, a fan unit, and a control system. The airflow directing unit includes a plurality of separately controlled air distribution segments. Each register unit includes a motorized damper and filter. The fan unit is connected to the airflow directing unit and to the register units through piping. The fan unit injects air into the airflow directing unit, and generates a vacuum force that causes exhaust air with airborne particles to be pulled into the register units and filtered by the filters within the register units. The control system selectively controls the air distribution segments of the airflow directing unit and the motorized dampers of the register units to generate alterable airflow patterns between the airflow directing unit and the register units in different zones within a room in which the airflow directing unit and the register units are disposed.

Abstract: A vehicle dryer includes an energy-conserving rotatable inlet butterfly valve to selectively admit or block air to a fan encased in a blower housing. The valve includes a plate mounted on a shaft that extends across the inlet portion of the blower housing. The plate is rotated by its shaft to either an opened position for admitting air into a blower housing, or a closed position for blocking air from entering into the blower housing. A crank arm is coupled to the valve shaft, and a pneumatic cylinder includes a piston rod for turning the crank arm through a ninety-degree angle, thereby rotating the valve plate between its opened and closed positions.
