Smoke Backward Cabinet Fan

The KBB-F series of cabinet centrifugal fan built-in double inlet double width backward curve of centrifugal fan with external of motor and are developed on the basis of advanced technology from European. The motor is isolated from the system airstream, enabling the unit for extracting contaminated air, operating in corrosive, hot, dusty, or hazardous conditions. This new types are used in super low noise, high rise buildings, kitchen hood and hazardous areas of industrial and commercial ventilation where large volumes of air are required at medium to high pressures. They are also an excellent choice in specialised HVAC system applications. It has the features of high efficiency, low noise, excellent performance, compact structure, easy installation and so on.
