Motorised Dampers

Dampers come in a variety of designs. Opposed blade dampers use a motor to open and close them. This damper design has the appearance of accordion or folding panels when closed, and metal slots when open.

Single blade dampers can use a motor to open and close them, or use a spring to close and a motor to open. This type will remain in the closed position at rest.  A single blade with spring open uses the motor to close, and is open at rest.

Non Return Dampers

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.
