Abstract: A mixed flow inline fan assembly includes an outer housing, a motor assembly disposed within the outer housing, a fan wheel disposed within the outer housing, where a shaft of the motor assembly is coupled to the fan wheel, and the fan wheel includes a hub, a plurality of blades coupled to the hub via first mechanical fasteners, and a shroud coupled to the plurality of blades via second mechanical fasteners

Abstract: An exhaust fan unit of a heating, ventilation, and/or air conditioning (HVAC) system includes an outer fluid path of a nozzle assembly of the exhaust fan unit defined by and between an outer wall of the nozzle assembly and an inner wall of the nozzle assembly, an inner fluid path of the nozzle assembly defined by and radially inward from the inner wall, and a plurality of entrainment ports extending from the outer wall to the inner wall and configured to enable environmental air to pass to the inner fluid path, where each entrainment port includes a bottom surface that tapers downwardly from the inner wall to the outer wall.

Abstract: Embodiments of the present disclosure are directed to an inline centrifugal mixed flow fan system that includes a wheel assembly disposed within an outer housing and comprising a hub cone, a plurality of fan blades directly coupled to and extending radially outward from the hub cone, and a shroud directly coupled to and at least partially radially surrounding the plurality of fan blades. The wheel assembly is configured to receive an air flow at an inlet axial end of the outer housing axially upstream of the wheel assembly, and to redirect the air flow axially downstream relative to a central longitudinal axis, circumferentially about the central longitudinal axis, and radially outward from the central longitudinal axis.

Abstract: A clamp for a battery cable, to be easily secured and removed from a battery terminal stud, the clamp including a main clamp body having a vertical bore extending therethrough which is adapted to receive the battery terminal stud therein, the clamp body further including a vertical channel extending from the vertical bore to a distal face of the clamp such that when confronting faces of the vertical channel are pushed towards one another, the vertical bore is tightened about the terminal stud so as to secure the clamp thereto.
