I do not fan but actually wind machine nominal: So, it is noisy and produces a veritable storm.
The volume is not a problem for me, however, is already being done at level 1 plenty of wind.
It would be a dream to be able to down regulate the speed.
However, I use them even in smaller rooms, here is the magic formula indirect ventilation: Just set in an appropriate angle against the ceiling and redirect the air so freely.
Fortunately, it is possible the postion adjusted continuously, almost parallel to the ground.
Since I had the high volume / wind power expected, the machine looks good and performs its service reliably, there also all the stars.
