7.10.2 Deflector
For optimal guidance of the air current, a deflector made of galvanized steel sheet can be mounted on the pressure-
side silencer (accessory).
The deflector as accessory for AJR/AJ8 is delivered in a separate package.
Before installing the jet fan, fasten the deflector on the silencer of the pressure side (see arrow).
Position the deflector fins so that after fastening the jet fan to the ceiling, the air flow is directed downwards at a
10° angle. It may be possible to readjust the fans afterwards depending on the structures located in the immediate
vicinity, such as girders.
