At first sight, this fan-box doesn't seem to be something special, but looking at it closely, you can see, that this is a real darling:
The in- and out-holes both have a diameter of ca. 15.5cm, and so fit the right matching part of 16cm diameter very well.
Still the effort and the noise insulation absolutely conform to the standard, even though the price of purchase rings hollow - but it's true!
