摘要： The subject invention relates to a fan housing, comprising a unitary molded structure formed from a material that has a flame spread rating of twenty five or less. The unitary molded structure comprises a base, an impeller housing centrally located next to the base, and a flow path located circumferentially around the impeller housing with one or more defined walls for directing air flow. An exhaust port receives air from the flow path and outputs air in a particular direction.
