Abstract
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.
