Abstract: A fire damper for an air distribution system includes a body defining a flow path and a closure means adapted to close the flow path when a temperature within the flow path exceeds a predetermined maximum temperature. A first flange is fixed to the body and a mounting means comprising a second flange is slidably engageable with and removable from the body. The mounting means comprises securing means for securing the mounting means to the body such that a building element through which the fire damper extends, in use, can be clamped between the first and second flanges. A flexible insulating sleeve configured for use with a fire damper, and a method of installing a fire damper, are also disclosed.

Abstract: A fire damper including a frame and a plurality of blades rotatably mounted to the frame such that each blade is rotatable about a respective rotational axis between an open rotational position and a closed rotational position, each blade including at least one substantially planar portion; and a side edge portion which is curved away from a plane of the substantially planar portion, wherein a first curved side edge portion of a first of the blades is adapted to engage a second curved side edge portion of a second of the blades, adjacent the first, when the blades are in the closed position; and wherein the first curved side edge portion curves in an opposite direction to the second curved side edge portion when the first and second blades are engaged.
