7.8.2 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.
