摘要： An exhaust fan assembly is provided for expelling contaminated air from a building. The assembly includes a plenum, a fan assembly attached to the plenum, and a windband mounted on top of the fan assembly. The fan assembly is constructed of cylindrical outer and inner walls which define a bearing chamber and surrounding annular space. A fan driven by a shaft extending downward from the bearing chamber draws exhaust air from the plenum and blows it up through the annular space to a nozzle at the top of the fan assembly.

摘要： An exhaust system for expelling air from a building includes an outlet nozzle that improves entrainment of ambient air with the building exhaust air. The improved air entrainment results in increased exhaust air dilution and plume height to better disperse the exhaust air away from the building. The nozzle has an H-shaped outlet configuration with two lateral outlet sections joined by a central transverse outlet section. The nozzle has a pair of outer lateral walls, a pair of outer transverse walls, and a pair of sloped inner lateral walls that angle outwards from near an inlet end of the nozzle towards corresponding outer lateral walls. The nozzle can be part of the exhaust system at the outlet side of the exhaust fan within a windband that aids in entraining ambient air with the exhaust air exiting the nozzle.

摘要： A B-channel for use in a damper frame or sleeve is disclosed which is formed from a blank of sheet metal. The blank has a rectangular barrier wall, a pair of side walls formed along two opposing edges and end walls formed along opposing edges of the barrier wall. The side walls and end walls are folded perpendicularly to the barrier wall and tabs are formed on the end walls to be folded into the planes of the side walls. The B-channel is particularly useful in conjunction with a fire damper sleeve.

摘要： A fan assembly in which all of the major structural components of the assembly are mechanically fastened together by non-welding means, such as mechanical fasteners, is disclosed. The disclosure also relates to a fan assembly in which the major structural components have planar segments separated by bend lines that approximate a curved shape, and that can be formed, for example, by a press brake machine. Such a construction can eliminate the necessity for rolling, welding, and painting of the structural components of the fan assembly.
