Non-return dampers are designed for automatic shut off of individual sections of an air conditioning system.
With the fan running, the degree of blade opening is a function of the air velocity. if the fan is turned off, the blades close automatically. In a multi fan installation this prevents back draught through the non-operating fans.
Permitted installation orientation: horizontal and vertical.
