Evacuation system
6.2 Fresh air
For maximum efficiency and the shortest possible drying time, it is important to ensure that fresh air
is able to enter the room from the outside in the same volume as that blown out of the room
To avoid draught in the room it is important to place the air inlet behind the machine.
The area of the air inlet opening must be five times the size of the exhaust pipe area. The
area of the inlet opening is the area through which the air can flow without resistance from the
grating/slatted cover.

Note!
Gratings/slatted covers often block half of the total fresh air vent area. Remember to take
this into account.
