Abstract: A centrifugal blower has a first housing section and a second housing section separated by a width of the centrifugal blower. The centrifugal blower also has an intake port extending through the first housing section and the second housing section along the width, and an outlet port formed by the first housing section and the second housing section. A dimension of the width continuously decreases as the outlet port is approached along a length of the centrifugal blower.

Abstract: A centrifugal blower includes a centrifugal fan having a fan wheel, the fan wheel has a rotational axis and blades extending radially outwardly from the fan wheel, a blower housing including a first panel and a second panel disposed on opposite sides of the centrifugal fan and extending transverse to the rotational axis of the fan wheel, and further including a wall extending about the rotational axis and between the first panel and the second panel, where the wall includes a flange having a cross-sectional camber geometry, an intake passage extending through the first panel and facilitating fluid flow into the fan wheel, and an outlet of the housing facilitating fluid flow out of the housing, the outlet formed by the first panel, the second panel, and the wall, where the flange extends outwardly from the outlet.

Abstract: A centrifugal blower includes a centrifugal fan having a fan wheel that is configured to rotate about a rotational axis. The centrifugal blower includes a blower housing having a first side panel, a second side panel, and a wall extending about the rotational axis and between the first and second side panels. The centrifugal blower also includes a cutoff plate that is configured to extend about the rotational axis, where the cutoff plate includes a first end with a flange having a camber geometry and a second end that is configured to overlap with the wall such that an amount of overlap between the second end and the wall is adjustable to adjust a position of the flange relative to the fan wheel. The centrifugal blower further includes an exhaust port defined by the first side panel, the second side panel, the wall, and the flange.
