Max and Min RPM

[fran.cesc]

Hi all,

I need to use a fan. I have calculated the internal curve of my system. I saw fan suppliers websites and got the characteristic curve for a fan which works in my range of interest. All the fan curves which I saw are calculated for a certain RPM. So I calculated the fan curves for different RPMs with the fan laws, in such a way I can calculate different working points.

My problem is that I did not find any indication about max and min RPM for a certain fan. So my question is: is there any rule of thumb which would allow me to estimate the max and min rpm at which a fan can rotate?

Thanks so much

Look at AMCA Standard 2408-60, for fan construction standards and their respective performance limits.
