Very good looking and sturdy.
Unfortunately didn't use this as the fan they sent was the wrong one and now they haven't got the one i want in stock so returned everything and got the 16 inch airlift fan instead but it was a very nice looking piece of kit and i would of been very happy to have used this.

Top bit of kit
Brilliant, sorted out the air coming into the property instantly! Felt warmer straight away, and looks very tidy and good quality. FOr the price of it as well, cant fault it at all.

Returned due to poor fitment
Well constructed but returned this item due to fitment issues.

Nicht mal eine Anschlagsdämpfung
Das größte Außenmaß ist 206mm nicht 200mm. Die Klappen schlagen hart an und sind ungedämpft. Schöne Optik, aber mehr sicher nicht

Highly recommend Great Quality item
This company puts out "quality" items Something we dont see to often anymore. This item works great when exhaust fan turns on and closes nicely when fan is off. I like the rubber gasket Keeps cold air from coming back into house BigBox stores carry similar item BUT not as well made and more money Highly recommend

Works great.
Installed vertically so didn't have the problems of function other people have. However it's a pity that the description is wrong. 1. It says that it is spring loaded. 2. It states that it can be installed horizontal!

Precision built
This is not the first AC Infinity product I've bought. I already had an AC Infinity humidity sensing fan with a quality level that impressed me, so I decided this was the best brand when I needed a back draft baffle for my 8 inch kitchen fan exhaust. Similar build quality. You'd think this was a turbine engine part.
