The difference between centrifugal fans and blowers
Centrifugal fan: Based on the principle that kinetic energy is converted into potential energy, it uses high speed rotating impeller to accelerate gas, then decelerate and change direction of flow, and then convert kinetic energy into potential energy (pressure). In a single-stage centrifugal fan, the gas enters the impeller from the axial direction, the gas flows through the impeller, changes into radial, and then enters the diffuser
The blower is one of the centrifugal fans!The direction of the air outlet of the centrifugal fan is the tangential direction of the impellerThe axial direction of the axial fan is in the axial direction of the impeller
In a diffuser, the gas changes the direction of the flow, causing a deceleration that converts kinetic energy into pressure energy. Pressure increases mainly in the impeller, followed by the expansion process. In a multistage centrifugal fan, the flow of air into the lower impeller with a reflux device produces higher pressure.
Centrifugal fans and blowers belong to two different categories, and can not be compared.Centrifugal fan is classified according to the principle of operation, there are two major categories of centrifugal and axial flow. The blower is classified according to its characteristics, and centrifugal and axial fans can be used as blowers.
