Industrial Dust exhaust centrifugal ventilation exhaust air ventilation draft fan
1. Fuction
11-62 series low-noise multi-wing centrifugal fan is designed for meeting the growing needs of industrial and environmental noise reduction. During design, the fan is used by a multi-objective design according to noise, efficiency, and other aerodynamic parameters, in order to realize the best performance of the whole fan with good aerodynamic performance. Impeller is to be strictly regulated by balancing, so that the fan possesses the features of steady working, low noise, little vibration, and long life. It is widely used to kitchen exhausting, fume extraction or ventilation purposes in canteens, hotels, restaurants, and other public places, and also be applied in food machinery, chemical machinery, plastics, machinery and other production devices.
2. Stype
Face from the motor side, the impeller whirls clockwise, which is called right rotation fan, shown "right", while the impeller whirls counterclockwise, called left rotation fan, shown "left".
The exit of the fan is shown by the outlet angle of case. The range of the outlet place is 0~180°, three kinds, which must be indicated when making order. Fan's transmission mode is A type.
3. Structure
The fan is mainly made up of impeller, chassis, inlet, motor and other parts.

The centrifugal fan is based on the principle of converting kinetic energy into potential energy, using a high-speed rotating impeller to accelerate the gas, then decelerate and change the flow direction, so that the kinetic energy is converted into potential energy (pressure). In a single-stage centrifugal fan, the gas enters the impeller from the axial direction, the gas changes to the radial direction as it flows through the impeller, and then enters the diffuser. In the diffuser, the gas changes the direction of flow and the increase in the cross-sectional area of the duct slows down the gas flow, which converts kinetic energy into pressure energy. The pressure increase occurs mainly in the impeller, and secondly in the diffusion process. In a multi-stage centrifugal fan, a recirculator is used to move the airflow to the next impeller, creating a higher pressure.
