BACKWARD CENTRIFUGAL FANS

 

EC fan motors are backward centrifugal fans. The disadvantage of this type of fan is that the air flow pattern is oriented horizontally rather than vertically, which can reduce efficiency. However, backward centrifugal fans offer several advantages over traditional vertical fans, such as lower noise levels and smaller dimensions.

 

EC backward centrifugal fans are a type of rotary fan that use centrifugal force to move air. This type of fan is often used in places where there is a lot of dust and smoke, since it can help to filter the air and remove pollutants.

 

An EC fan is a simple device that is often overlooked in the design of wind turbines, but can have a significant impact on their performance. Backward centrifugal fans are often used to improve the efficiency of EC fans by reducing the amount of energy wasted as air is pulled in and pushed out.

 

 

Uses of EC backward centrifugal fans 

 

An EC backward centrifugal fan is a type of air-conditioning fan that uses the principle of centrifugal force to move air. This type of fan is often used in spaces where large amounts of air movement are necessary, such as factories and warehouses. They are also popular for use in small home offices, because they are not as bulky as traditional fans and can be placed more discreetly.

 

EC backward centrifugal fans are widely used in many industrial and commercial fields, such as food processing, pharmaceuticals, printing and dyeing, metalworking, and automobile assembly. These fans have been found to be efficient in reducing the pollution levels in the surrounding area.

 

 

The working principle of centrifugal fan

 

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, change the flow direction, and convert the kinetic energy into potential energy (pressure). In a single-stage centrifugal fan, the gas enters the impeller from the axial direction, changes to the radial direction when the gas flows through the impeller, and then enters the diffuser.

 

In the diffuser, the gas changes the direction of flow and the cross-sectional area of the pipe increases to decelerate the gas flow. This deceleration effect converts kinetic energy into pressure energy. The increase in pressure mainly occurs in the impeller, followed by the expansion process. In a multi-stage centrifugal fan, a refluxer is used to make the air flow into the next impeller, generating higher pressure.
