A fan trays assembly is made of one or small number of cast or injection molded (collectively "cast") components. Each component can be cast of plastic, metal or another material. One of the components of the fan tray includes a front wall, a back wall, two side walls, an inner wall defining a Venturi and a motor housing suspended within the Venturi by one or more structural members. The walls, the motor housing and the structural member(s) are all formed as a single casting. Casting these pieces together reduces the complexity and cost of manufacturing the fan trays. Multi-fan fan trays and modular fan trays can be similarly made.
