I have driven some of them as 300 hz , at which they saturate and stop rotation . At 120hz I am getting 7200 rpms out the fans. Hatichi builds fractional hp VFD's that can be run on 220 volt single phase and the VFD converts single phase to 3 phase. That feature is quite handy and they are easy to set up.</DIV>

<DIV>True, if you need psi of pressure boost not inches of water. I will try to add numbers to this post later today. </DIV>

volume vac system to move solids. Les Freeman ..you would need to gear up that turbocharger fan so it can do turbocharger speeds, they easily exceed e.g. 136000rpm, for common automotive sizes. -- ..med vennlig hilsen = with Kind Regards from Arnt... ;o) ...with a number of polar bear hunters in his ancestry...
