Evacuation system
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.
Fig. 1 To avoid a draught in the room, it is
advisable to place the air inlet behind the dryer.
Fig. 2 The area of the air inlet opening must be 5
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.
See table on the following page.
Note!
Gratings/slatted covers often block half of
the total fresh air vent area. Remember to take
this into account
The resistance in the grating/slats on the air inlet
cover plate should not exceed 10 Pa (0.1 mbar).
