Inquiry (采购产品): rheostat I have purchased an air curtain which, at full power, is much stronger than I need. Do you sell rheostats or high-low power switches. I need to lower the velocity of the fans. (The model I have is 120 volts and 42 inches wide.) **** Hidden Message ***** Michael Clutter 30305 Company: (self) E-mail: michaelclutter@earthlink.net **** Hidden Message ***** michaelclutter@earthlink.net
