Gaggenau AL400721 Brochure

Planning as a cooktop ventilation wall/island (W/I) up to max. 120 cm distance to 
the cooktop.
For larger distances planning as room ventilation (R) with air exchange rates 
10 to 12 times the room volume. 

The given airfl ow of the remote fan units will be reduced by the diff erent ducting 
types between fi lter modules and AR 400/401 as well as by the further ducting. 
For additional ducting chose the confi guration with higher airfl ow.

Bold print: favoured confi guration
Regular print: possible confi guration
Other: – Not possible due to performance or ducting reasons

Respect the positioning of the remote fan units and the run of the ducts.

Modules of ceiling ventilation:
F = Filter module (FL = in-line confi guration)
CL = Control module with light
CO = Control module without
L = Light module
