Abstract
A furnace blower has an inexpensive and compact coaxially arranged simplified construction that includes an electric motor having a shell with radially projecting fins that is press-fit into a cylindrical blower housing and a combustion tube that is also press-fit into the blower housing where the interior of a combustion tube is positioned in close proximity to a fan on the motor shaft. The press-fit assembly of the motor into the blower housing as well as the combustion tube into the blower housing simplifies the construction of the furnace blower and reduces its manufacturing costs. The furnace blower is also smaller than prior art furnace blowers which enables it to be readily retrofit into conventional furnaces in place of prior art furnace blowers.
