The KB series (KBAD – 3 phase, KBAE – single phase) is a range of high quality commercial extraction fans, manufactured by innovative manufacturing partner Rosenberg in Germany. the KB series of fans are driven by motors located out of the air-stream, allowing the impeller to operate at up to 100°, while the housing remains cool due to the manufactured thermally insulated skin. The motorised impeller is assembled to a hinged door, which provides rapid access to the fan for inspection and cleaning.
