Smoke Centrifugal Fan | Cabinet Type Centrifugal Fan
BF Model Features:
: Material Properties
: The case is made of high quality DKP and high quality galvanized steel plate with electrostatic powder coating. The surface has the properties of heat and moisture resistant, not easy to hurt, bright and beautiful colour. The case made of galvanised steel are joined or welded into a worm-shaped shell, which maintains the original lustre and pattern of galvanised steel. All are moisture and rust resistant, beautiful and durable. The worm tongue part of the housing adopts a new type of anechoic structure which has a good muffling effect.
: Fan Structure
: The impeller is the forward curve multi-wings type. All parts are stamped from steel sheet moulds. The impeller is adjusted by static and dynamic balance, with good aerodynamic performance. The impeller is flanged to the motor as one piece and installed in the casing, its transmission loss is zero, which improves the efficiency of the whole machine. BF series fan uses external rotor motor, dual air inlet structure.
: Benefits
: It can meet different operating conditions for air exhaust equipment.It has three speeds which will save energy consumption. Featured by smooth running, low noise, small size, light weight and convinent maintenance.
: Usage Area
: Fan is widely used for ventilation in air conditioning systems in buildings, factories, entertainment place, hotels, malls, hosiptals, cinemas, labtories, schools etc.
