1. Is it necessary to use frequency converter on axial fan?
Whether it is necessary to use frequency converter on axial flow fan, from a professional point of view, it is necessary to look at the actual situation and use demand. If you do not use frequency converter, axial flow fan can be used normally, and get the desired purpose and effect. However, the use of frequency converter can improve the performance and effect of the fan, because the transducer can achieve energy saving and speed regulation, while providing some protection functions.
2.Should axial fan or centrifugal fan be used for large suction force?
If you want to get a large suction force, you should choose a centrifugal fan instead of an axial fan for the specific type of fan that should be used, because at pressure the axial flow fan is not as large as the centrifugal fan, so in terms of suction force, The axial flow fan is not as good as the centrifugal fan.
3. Are axial flow fans available in combined air conditioning units?
The axial flow fan can not be used in the combined air conditioning unit because it can not meet the requirements of the air conditioning unit in the total air volume. In addition, the static pressure requirement of the combined air conditioning unit is very high, that is, the static pressure value of the outlet air is required to be large, but the axial flow fan cannot meet this requirement, so the fan is also not applicable.
4. In order to achieve pressurized air supply, should an axial flow fan, a centrifugal fan, or some other fan be used?
In order to achieve pressurized air supply, both centrifugal and pressurized fans can be used, but in the specific models of centrifugal fans, they are for 9-19 and 9-26. As for the axial fan, it is not suitable for use because it can not meet this requirement.http://www.jnblower.com/
