Extractor fans for concealed installation

Hidden installation

— an installation in which the fan is placed entirely in the duct. This option can be very useful in cases where you need to maintain a certain design in the room, and extractor fans do not match this design. Nevertheless, note that sometimes manufacturers call extractor fans hidden: most of the case of such devices is hidden in the wall, but some part is still located outside. Therefore, when buying, it makes sense to additionally find out all the details of installation.
