Please read the following paragraph for product review. It could be a faulty product or design issue. Nevertheless seller was very helpful and accepted refund, replacement and recommended another item. Nevertheless I keep the installed product.
After using for a day, fan started to make abnormal noise. Fortunately it is kitchen fan, I looked at the back and thought it is the back cover which stops in flow.
I removed the back cover. I started the fan and it worked so smoothly I could not believe how silence it is. Then I realized the plastic fan blade was detached and dropped. The connection to the motor is so flimsy that it easily disconnect. I will return it, since even another one has the same issue the connection of fan blade to motor is a soft plastic assembly which is a design fault
Extractors fan is not a complicated equipment. What makes a difference is build.
Unfortunateley I have only cons;
1-The previous one i bought for bathroon, the front screw is experiencing corrosion and became red and yellow around it, very ugly and unprofessional.
2-This one, for kitchen, the cover/windows behind it, where it should protect it from in-flow is loose and the spings are so weak that it flaps all the time.
3-no cable, wire,...
4-no screws for simple connection
I though vent-axia was a quality to rely on. After buying two of them, one for bathroom and one for kitchen; I am stuck with them. Not recommended at all.
