There are many models of Roots blowers in the market, different models, their pressure range, flow range and supporting motors are not the same, so how do we choose? In the comparison of the parameter comparison table, we most need to understand the following aspects.

The first is the caliber, under normal circumstances, the caliber size of the fan is the same as the mantissa number of the model, but there will be a model distinction, such as many customers see the parameter table written above is 65A, 65B, this number represents the caliber of the two models are consistent, but the model is different.

The second is the speed, some customers for the speed of Roots blower is also required, in some technical agreements, we have seen a lot of customers for the speed of the fan has certain requirements. The speed of the fan affects the air volume, why is there a requirement for the speed? In addition to industry reasons, although different speeds can meet the same working condition, we should try to choose the speed to match. The higher the speed, the faster the wear of the blower, the shorter the service life.

The third type of gas, if it is to transport biogas, gas and other special gases, the transport of such gases requires special sealing, so if you transport such gases, the Roots blower will have certain differences in manufacturing, and there will be certain differences in sealing methods.

The fourth is the motor power, the motor power is a matching parameter, if the blower is determined according to the pressure and air volume, then the motor power is basically confirmed, which is determined on the standard selection sample, not randomly replaced, the motor power may be large or small, which is to be selected according to the actual use.

What if there are no parameters? It can only be started from the way of use, if you are applied to the sewage treatment industry, then you can explain the specifications and water depth with the factory, so that our professionals can recommend you.
