Speed Control Unit for Doran Darkroom Fans

When installing a darkroom ventilation fan, it's an excellent idea to install a speed control unit.  This allows you to reduce the fan speed when maximum air flow is not required. This unit can be wired into the fan circuit much like a light switch, and therefore can be positioned where it is most convenient. The kit includes the switch, faceplate, faceplate mounting screws, and installation instructions. UL approved.
