Hi,
I have Vansal high speed 9" exhaust fan, its very effective but only problem is that it is causing too much noise. The noise is not coming from mount or anywhere else but from the high speed air passing through it. If I test it without fan blades, the motor is quiet. Please suggest me way to make it silent without effective its air flow capacity. I don't want to change the fan but only want to use it as I don't want to spend more money. So please don't advice to buy new costly fan. This fan is already costly because similar fan without bearing system comes on half of the price of it.
Thanks for reading and advice.
