tube with an axial length between a first end 44 and a second end 46 of the cylinder that is sufficiently large to contain the motor 36 within the housing the housing has an exterior surface 48 and an opposite interior surface 52 that surrounds a hollow interior volume 54 of the housing the first end 44 of the housing defines an inlet end 56 of the furnace blower as will be explained a circular housing end wall 58 is press fit into the second end 46 of the cylindrical housing 34 the end wall 58 is also preferably of stamped steel construction as opposed to the cast iron construction of prior art furnace blower housings the end wall 58 is formed with an annular shoulder 62 around its periphery that is press fit into the blower housing second end 46 and engages in a friction fit connection against the housing interior surface 52 as shown in fig3 by a press fit connection between the blower housing 34 and the end wall shoulder 62 what is meant is a tight friction fit or interference fit between these component parts that enables them to be held securely together without the use of separate fasteners as is necessary in assembling cast iron housing sections of prior art furnace blowers the housing end wall 58 is also provided with a circular opening 64 at its center that defines.
