摘要： Fan assemblies, and in particular fan wheels and stator assemblies for fan assemblies, are disclosed. In one embodiment, the fan wheel includes a wheel back having an outer surface forming one of a curved dome-shape and a truncated cone-shape. The fan wheel may also include a plurality of fan blades radially spaced about and mounted to the outer surface of the wheel back. In one embodiment, each of the fan blades is formed from a segment of an airfoil-shaped aluminum extrusion defining at least one internal cavity. The fan blade first ends can be provided with a compound cut profile with at least one curved cut such that the first end of the blade is mounted flush to the wheel back outer surface. The stator assembly can also be provided with a plurality of stator blades formed from airfoil-shaped aluminum extrusion segments and provided with compound cut profiles.

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： A gas-fired heating and ventilation system includes a blower which draws air through a recirculation damper from a building and through a direct gas-fired burner from a fresh air inlet. A passive control damper is mounted to bypass air around the burner and to thereby regulate the air flow through the burner for optimum combustion over a wide range of operating conditions.

摘要： A ventilation system for institutional and commercial cooking equipment includes a hood which is placed over the equipment and which attaches to an exhaust duct and fan that removes a relatively constant volume of air from beneath the hood. A make-up air supply divides to form a fresh air duct that connects to the hood and a tempered air duct which also connects to the hood. The fresh air is directed beneath the hood by fresh air registers and the tempered air is directed into the surrounding room by tempered air registers. The relative amounts of fresh air and tempered air can be changed by a damper, but the damper does not significantly alter the total amount of supplied make-up air. The system can thus be adjusted to use more or less tempered air as various combinations of cooking equipment are used without affecting the overall balance of exhaust air and make-up air.
摘要翻译：用于机构和商业烹饪设备的通风系统包括放置在设备上并且附接到排气管和风扇的罩，其从罩下方去除相对恒定体积的空气。补充空气供应器分开形成连接到发动机罩的新鲜空气管道和也连接到发动机罩的回火空气管道。新鲜空气通过新鲜空气寄存器引导到发动机罩下方，回火空气通过回火空气寄存器引导到周围的房间。新鲜空气和回火空气的相对量可以通过阻尼器改变，但阻尼器不会显着改变供应的补充空气的总量。因此，可以调节系统以使用或多或少的回火空气，因为使用烹饪设备的各种组合而不影响排气和补充空气的总体平衡。

摘要： A fan comprising a motor, an impeller, a curb cap, a support pan, a first conduit, and a second conduit. The impeller is rotatably coupled to the motor about a longitudinal axis. The curb cap is configured for interaction with a roof curb. The curb cap includes an airflow opening, a first conduit opening, and a second conduit opening. The support pan supports the motor. The first electrically insulative conduit extends between the support pan and the first conduit opening along a first conduit axis. The second electrically insulative conduit extends between the support pan and the second conduit opening along a second conduit axis. In a plane perpendicular to the longitudinal axis, a central angle between the first conduit axis, the longitudinal axis, and the second conduit axis is greater than or equal to ninety degrees and less than or equal to one hundred and eighty degrees.

摘要： A fan assembly configured to address expansion losses and associated noises in centrifugal fans modifies the blades and housing to enhance the efficiency of air flow. The fan assembly can include a centrifugal fan wheel and shaped housing incorporating curved walls that guide the airflow along an efficient path, minimizing abrupt directional changes and resulting in improved energy efficiency and reduced noise levels compared to conventional housed centrifugal fans. Additionally, fan assembly includes a low-profile, energy-efficient motor positioned within an interior region defined by the centrifugal fan wheel, reducing the overall size of the fan assembly. In embodiments, the fan assemblies can function as standalone fans or be arranged in an array configuration to effectively move large volumes of air.

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.
