The BN series are designed specifically to handle high temperatures or other industrial airstreams that may shorten the life of the fan motor. The motor is isolated from the system airstream, enabling the unit for extracting contaminated air, operating in corrosive, hot, dusty, or hazardous conditions. They are also an excellent choice in specialised HVAC system and kitchen hood applications. The aerofoil axial impellers were developed with advanced technologies of London Fan company, a world famous axial impeller manufacture which was set up in 1928. They are designed to bear the BS and ISO standard for air performance, sound data and efficiency which are equivalent to AMCA and DIN standard.
