This is my first post and I am not very electrically inclined so please bear with me. I am building a coffee roasting machine. I already have a 2hp blower that runs at 3750 rpm. Is it possibe to add a part so that I can vary the rpm's. Maybe something like a rheostat? I am running this unit on 220 power. I believe that I will need to significantly slow down this machine.
thanks in advance.
