Abstract
A blower assembly including a blower housing having a side wall with a first portion extending from the initial cutoff through an angle of at least 45° or more, the first portion having a radius which is substantially constant or which increases at a relatively small rate. The side wall additionally includes a second portion, extending from the end of the first portion to the outlet, which forms a continuous curve with the first portion and has an increasing radius which is increasing at a larger rate and has a rate of increase that is also increasing with housing angle. The shape of the side wall allows a reduction in the overall size of the blower housing for a given size of impeller.
