A blower for a heating, ventilation, air conditioning, and refrigeration (HVACR) unit, comprising:
- a plurality of blower sections, each section including:
- a first shroud,
- a second shroud spaced from the first shroud in a direction of a longitudinal axis of the blower, and
- a blade, the blade being formed such that a first end of the blade is joined with the first shroud and a second end of the blade is joined with the second shroud;
- and
- a band secured to the plurality of blower sections,
- wherein the first shroud of each of the plurality of blower sections includes a protrusion on a first radial edge of the first shroud and an opening on a second radial edge of the first shroud, the first and second radial edges being spaced circumferentially from each other.
A method of manufacturing a blower for a heating, ventilation, air conditioning, and refrigeration (HVACR) unit, comprising:
- forming a plurality of sections of the blower, each section including a first shroud, a second shroud spaced from the first shroud in a direction of a longitudinal axis of the blower, and a blade, the blade being formed such that a first end of the blade is joined with the first shroud and a second end of the blade is joined with the second shroud;
- securing a band to the plurality of sections, and
- assembling the plurality of sections together to form the blower,
- wherein the assembling includes inserting a protrusion on a first radial edge of the first shroud of a first of the plurality of sections into an opening on a second radial edge of the first shroud on a second of the plurality of sections.
A blower for a heating, ventilation, air conditioning, and refrigeration (HVACR) unit, comprising:
- a plurality of blower sections, each section including:
- a first shroud,
- a second shroud spaced from the first shroud in a direction of a longitudinal axis of the blower, and
- a blade, the blade being formed such that a first end of the blade is joined with the first shroud and a second end of the blade is joined with the second shroud;
- and
- a band secured to at least one aperture of the first shroud of the plurality of blower sections by a fastener.
