High Temperature Exhaust Fan
The RSD is available in three sizes with three different controllers. The universal Fan Speed Controller (FSC) controls the variable speed of the RSD fan to maintain proper draft. The MUC controller can also control a mechanical damper and is wired with alarm contacts. With the optional H100 controller, the fan speed is automatically modulated to maintain a constant negative pressure in the flue as accurate as 0.01. Add an available rain-shield to block out additional moisture.
