Product Description

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. There are two types of damper can be installed horizontally and vertically.
