Abstract
A furnace distribution blower for use in a conventional furnace that is configured without a blower housing. The furnace distribution blower includes a backward curved impeller mounted around a drive motor having a central drive shaft. The drive motor rotates the backward curved impeller to draw air into the inlet of the impeller. Preferably, the inlet of the impeller is closely mounted to an inlet bell of the furnace. The furnace distribution blower can be mounted to a support tray such that the furnace distribution blower can be moved from an operating position in which the impeller is positioned beneath the heat exchanger and a service position in which the impeller is removed from within the furnace housing. The elimination of the blower housing decreases the cost of the furnace distribution blower as compared to a blower having a housing.
