[2021/22] KDK exhaust fan 15WUD

At a friend’s house. Installed sometime late 2021/this year. These fans spin surprisingly quickly, and can be loud when in an enclosed space with little room for airflow - such as this one.

hi,
May I ask How's the set up like? is the fan sharing the power source with lighting; meaning the fan can only turn on upon turning on the lights? What if i just want to leave the ventilation on even when toilet ligthing is off.
