Abstract (en)

[origin: WO2007097715A1] A ventilation or exhaust system, having ducting, and a fan assembly for placement in ducting of a ventilation or exhaust system for an environment space. The fan assembly has a motor having an output shaft, a fan mounted on the output shaft, and a brake mounted for operation on the motor. The brake is operable for stopping rotation of the motor upon a detection of a prescribed situation one or more of: the environmental space, and the ducting. Also included is a valve assembly having a valve member for placement in the ducting for movement between a first position where the ducting is substantially open, and a second position where the ducting is substantially closed. The valve member is adapted to move from the first position to the second position in response to at least one detection of a prescribed situation. At least one detector is provided for detecting a prescribed situation, the detector being for controlling the operation of the brake of the fan assembly, and the valve assembly, in response to the detecting.
