11. Exhaust air pipeline

1
1: Air outlet to outdoors
2: Air outlet via an air shaft
• The exhaust air line should be as short
and straight as possible.
• To avoid excessive noise or a reduced
extraction capacity the diameter of
the exhaust air pipeline should not be
less than 150 mm.
• Use or form only large radius bends.
Small radius bends reduce the extrac-
tion capacity of the hood.
• Use only smooth pipelines or fl exible
hoses of non-fl ammable materials for
the exhaust air pipeline
• If the exhaust air pipeline is horizon-
tally routed, there must be a minimum
gradient of 1 cm per metre or an inc-
lination angle of 2°. (Fig. C) Otherwise
condensation water could run into the
extractor hood motor.
• If the exhaust air is directed into an
exhaust air duct, the end of the entry
fi tting must be directed in the direc-
tion of fl ow.
• If the exhaust air pipeline is routed
though cool rooms, loft s etc. there can
2
be a large temperature drop within
the individual parts of the pipeline,
resulting in sweating or condensation
water production. This renders outlet
pipeline insulation necessary.
• In some cases a condensation water
barrier must be installed in addition
to adequate insulation
