Air fan for living room - directs air via perforated surface and control grid into room

摘要

The fan delivers air at relatively low speed into a living room. The air current is directed to a distribution chamber (11) from the inlet (12) and then through a perforated surface (13) into the room. The air is distributed over the entire perforated surface and is discharged from the latter at right angles to it via an internal control grid (21). To avoid restricting the air jets and distribute them as widely as possible there are control members on the sidewalls of the fan unit (10), and there is an expansion chamber (14) between the inlet and the distribution chamber.
