3. About wiring>>Each exhaust fan has a 40cm standard wire, which is convenient for you to connect to the circuit. The installation position and layout are different for each customer, so there is no design plug, you can configure the plug or power switch according to your own needs.
4. About noise>>30-40 dB, just like the sound of mosquitoes flying around the ear, everyone's sensitivity to sound is different. If you are installed in the bedroom, please try to stay away from your bed.
