Abstract

A backdraught shutter for a ventilating fan defining an air flow path through the fan is designed to close off the air flow path when the fan is not operational. The shutter comprises a plurality of blades (2,3,4) mounted upon a supporting member for pivotal movement between positions corresponding to the closure and opening of the air flow path through the fan. The blades (2,3,4) tend to the closed position under the action of gravity when the shutter is in a first, predetermined position and the shutter is provided with means for retaining the blades in the closed position when the fan is in a second, different orientation and the fan is not operational, the retaining means permitting automatic movement of the blades to the open position when the fan is switched on. The shutter may be formed integrally with the fan or formed as a separate accessory. <IMAGE>
