Industrial blowers are mechanical equipment that can move gas or air, and are used in a variety of industrial processes and applications that require enhanced gas or air flow. By rotating the fan impeller composed of multiple fan blades, the flow of airflow can be increased. The wind wheel accelerates the air entering the blower housing and pushes it out through the housing outlet, thereby providing air for the application. The fan wheel is usually rotated by an electric motor or a turbine. There are two types of blowers, centrifugal and axial, which are classified according to the direction of airflow. Depending on your application, a variety of blower design options are available, and the blower should be selected so that it can provide long-term effective service.
Design aspect
When designing an industrial blower, there are several aspects to consider, with the main focus being the application selected for the blower. The specific flow and pressure requirements of the application are the main factors to be considered in fan design. Another factor to consider is the airflow characteristics of the application, such as whether the blower will operate in a harsh environment. The typical element of designing a centrifuge is to operate the unit within a narrow working pressure range. When designing the blower, it is necessary to ensure that the eddy and turbulence in the blower housing are also restricted to minimize blade wear.


Selection and installation of blower
Generally, the choice of blower is based on its service life, performance and efficiency. However, the noise characteristics of the blower must also be considered, especially when the blower is used in the HVAC system. When installing the blower, it is important to install it on a solid base to prevent resonance.
Flow control
In some applications, flow control will also be necessary. In this case, a flow control method must be selected. The two main methods of controlling flow are variable speed and industrial damper. The speed change is achieved by controlling the driver's speed. For this, please use variable frequency AC controllers, hydraulic variable speed drives, and DC motors and drives. On the other hand, industrial dampers control flow by restricting air flow. Industrial blowers can use a variety of dampers, including radial inlet dampers, louvered intake box dampers and exhaust dampers.
