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.

Abstract: The present disclosure relates to a flow generating device for a heating, ventilation, and/or air conditioning system. The flow generating device includes a housing having a channel defining a flow path of a fluid and a fan blade having a rotational axis extending through the channel, where the fan blade is configured to rotate to force the fluid along the flow path. A portion of the fan blade axially protrudes beyond the channel in a direction generally aligned with the flow path and a winglet extends from the portion of the fan blade.
