Dear All, I need to provide a source of the airflow to my experiments. The range of air velocities that I need is 2m/s to 20m/s. A source of airflow (I think it will be an air blower) will need to be powerful enough to overcome some significant resistances, given to the airflow by physical obstacles (therefore, fans may not be suitable for my experiments). I think about purchase of this device https://www.amazon.com/Professional-Blower-Extraction-220Volt-Europe/dp/B06ZYYTV9W
This device has adjustment of the airflow velocity, but for some experiments, I will need pretty low velocities (beyond a regular spec of this or similar devices). Therefore, I am looking for ways of extra adjustment of such blower speed. I came across the VFD (Variable Frequency Drive). - I wonder whether control of the linked blower by VFD will work in order to get velocities as low as 2m/s. - I also wonder whether application of VFD is the most optimum solution for reduction of air blower speed. Any advice and help on this would be much appreciated. Thank you. Regards.
