Suncourt Duct Booster Fans & DS100 Thermostat

DB fans: These fans install into home or office ductwork for out-of-view, year-round comfort. Operate by wiring directly to the main blower of your heating/cooling system, an on/off switch, VS200 speed controller, or Suncourt's DuctStat® Plug-In Thermostat™. With balanced Valox, aluminum or polycarbonate (Lexan) blades they are ideal for boosting supply air, return air, or venting. DS100 or other controls not included.

Must be manually switched between heat/cool modes in the winter and in the summer. 120 VAC.
