[sudo-discuss] Ventilation fan installed over sudoroom!

[Autonomous]

I would also add that this type of exhaust fan is not designed for
continuous use due to overheating and the potential fire hazard risk. I
have a similar type of fan installed in a 4800 sqft building that is cycled
30 minutes on and 30 minutes off. It can become quite hot after 30 minutes
especially in warm weather.
