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.

The motor-impeller unit can be pivoted for cleaning purposes by the generous operating door. The door hinge DIN right can be easily be converted to DIN left. Connecting pieces fit standard pipes.
