181 || Wash Wash Public Restrooms with an exhaust ventilator Why waste energy and money by ventilating public spaces continuously at maximum airflow? The flexibility of the Fantech FRD series allows you the ability to run the ventilation fan at a low rate when the restroom is unoccupied and at a higher rate during periods of high occupation with the use of a simple occupancy sensor. The fans maximum ventilation rate can be controlled or dialed down to the required airflow rate by the use of an inexpensive line voltage speed control such as the WC15 Speed Control On/Off. This eliminates noise and saves energy. The Fantech FRD series is 100% speed controllable and offers a swing out motor compartment for cleaning and maintenance. 1.
