Applications
Centrifugal blower fans like the Kooltronic KBB35 are standard equipment for forced-air cooling of electronics enclosures, control panels, and equipment cabinets. Unlike axial fans, centrifugal blowers move air at higher static pressure, making them well-suited for ducted or restricted-flow installations where air must be pushed through baffles, filters, or heat exchangers. Kooltronic has long manufactured this type of blower specifically for electronics thermal management — they are commonly used in industrial control panels, rack-mount cabinets, broadcast equipment enclosures, and similar applications where reliable, directed airflow is needed. The KBB35 dates from the early 1980s but the centrifugal blower design it represents remains in active use across industrial and electronics cooling applications today. Units of this type are also sought for maintenance and replacement in legacy equipment still in service.
This Kooltronic KBB35 115V Centrifugal Blower Fan has been inspected and appears to be in good used condition. The grey steel scroll housing is intact with no visible cracks or deformation, and the impeller blades visible through the outlet appear undamaged. The motor housing shows light surface marks consistent with normal storage and handling wear. The hardwired leads are present and intact.
