Twin fan speed controllers (4.5amp)

This unique product represents a real step forwards in automatic temperature control. Unlike other controllers that simply shunt fans from idle to full speed after temperature is exceeded, the Twin Controller automatically calculates the exact running speed for your fans to maintain the temperature you set. This new method provides more accurate temperature control, limits fan noise and guarantees negative pressure inside the room. Simply plug in your fans set the temperature and the Twin Controller will take care of the rest.
