Air connections
The air take-off point should be selected with con-
sideration to a high average air temperature and
the requisite air volume of 350 m
3
/h. Air inlets and
outlets are arranged at an angle at the rear
. In
order to keep the air resistance to a minimum, the
air intake and exhaust duct should be configured
as straight as possible, with a minimum smooth
tube cross-section of Ø 150 mm. The entire tube
length for the intake and exhaust air should not be
more than 12 m, whereby the installation of no
more than 3 right-angled elbows is permitted. The
entire tube length must be reduced by 1 m with
every additional elbow. In order to prevent the dis-
charge of condensate water, the air lines must be
laid horizontally or with a slight downward gradient
towards the suction/blow-out openings, or the
installation of an evaporation pouch is required.
