Selection of fans
Thread Content
I currently need a pressure of around 2000 Pa, a flow rate of around 4 m3/h, operating at room temperature, and the medium to be transported is air. I would like to ask the experts: what model should I choose?
The fans vary depending on the manufacturer you choose, and their models are also different. When selecting a model, we determine the fan type based on the parameters provided by the equipment manufacturer.
That’s right; the poster should still collect samples from several manufacturers and get in touch with them to update the information in order to determine the models.
The fans are more or less similar; just choose one based on your needs, such as the Model 4 centrifugal ventilator, Model 4.
Who can explain what the formulas or curves look like, what their relationship is, and how to make the selection?
For fans with low pressure and such a small flow rate, you can check online and select a model that meets your requirements.
Choose the smallest one from 4–68, and it can be used.
It is best to list the required parameters and provide them to the manufacturer, as this will yield more accurate results. We often do this
2000 Pascals, 4 cubic meters per hour. Did you make a mistake? Indeed, it’s really hard to find. Because the air volume is too, too low!
Just buy an ordinary aerator; they are available in every city.
Be careful to convert the air volume from operating conditions to standard conditions.
4m3/h？ Pressure 2000 Pa? I guess no such fans exist in the current sample of fan manufacturers? It has to be customized by the manufacturer!
You’re right; it’s indeed hard to choose, as the sizes are too small. You can go straight to the fan manufacturers and ask them to make a selection. If there are no standard products that meet the requirements, they can also create custom designs for you. I think options like 9-19 or 9-26 would be cheaper than 4-68
Ask the fan manufacturer for a sample to check against
