Commercial kitchens demand that exhaust fans are of sufficient quality to withstand the rigours of
continuous bombardment with hot, greasy air. Furthermore, once the fan is totally contaminated, out-ofbalance
and failing to exhaust the right amount of air, it has to be cleaned efficiently with minimum
down-time or risk of damage to the impeller.
The solution offered by Axair Fans UK Limited is the Rosenberg KB series; purpose designed fans for
professional kitchens.
The KB series is a high quality product, manufactured in Germany for world markets. It is driven by
motors located out of the air-stream, allowing the impeller to operate at up to 100°, the housing
remaining cool through having a thermally insulated skin. The motorised impeller is assembled to a
hinged door, which provides rapid access to the fan for inspection and cleaning.
There are two types of fan. The smaller units from Ø180 to 280 have forward-curved steel impellers
whilst from Ø315 to 500 they are backward-curved and in aluminium. Air flow rates vary up to 8000³/h
and pressures up to 1900pascals. Motors may be specified as single or three phase and are available
with guarded external rotor motor or standard industrial motor.
