Schweigen also has a cashback promo, $350 for spending >= $3K, for purchases before October 3 (though this appears to be a forever-extending promo).
Less with cashrewards/shopback and gift cards.
For a 120cm, it is on the pricier end of the scale but the cashback alleviates this somewhat (plus it is "silent").
Externally mounted 3200m3 motor - there are specific install instructions (needs a separate mount on the wall, ducting has a minimum run length etc).
RRP is a hardly normal $5800. schweigen 2nds outlet is $3800.
Beware! They are well known for defects in the rangehood's control buttons which start failing only after a few months of light use. Basically they not longer hold on when pressed.
I've opened a couple of support cases with them, just plain horrible. They plainly refused to fix them and blame it on a wrong installation (for both claims) even though I used 2 different very reliable companies on each house. Besides, there is nothing too complex about the installation as explained to me by both trade companies.
