Airflow (m
3
/h)
Available pressure, Pa
Air intake only through the exhaust air sleeve
Air intake through both the exhaust air and
extract air sleeves
Supplied fan output.
Fan output, W
Example, reading off the fan output
Requirements: Airflow 200 m
3
/h. Required pressure in-
crease (=pressure drop in duct system) 270 Pa.
To select curve:
Read off the cutting point between the desired airflow •
and required pressure increase.
Select the closest solid lined curve (in this case curve •
H).
To read off the fan output:
Look at the dotted line for the selected curve (in this •
case curve H), and read off the fan output on the
right-hand axis. In this instance, the fan output is 70
W at an airflow of 200 m
3
/h.
Exhaust air duct
The kitchen flue must not be connected to FIGHTER 640P.
Adjustment
See the section “Setting the ventilation”.
