#$%^&*AU2018102142A420191121.pdf#####ABSTRACT A blower including a housing at least partially defining a chamber, a motor including a drive shaft defining a rotational axis, an impeller driven by the motor to generate an air flow in the chamber, and a coupler operably connected between the drive shaft and the impeller. The chamber may have an axial height which increases from a position proximate a back plate to a position spaced from the back plate. The chamber may have a non-circular crosssection proximate a chamber outlet, and a tube assembly in fluid communication with the chamber may have a tube inlet with a non-circular cross-section. The impeller may define two separate airflow paths each having an inlet and an outlet. 10543106_1 (GHMatters) P109468.AU1/14 50 14 10 154 5A 18 /I252 22 5B / 5A / 30 5B FIG. 1
