Exhaust air pipe
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 extraction
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 horizontally routed, there must be a minimum gradient
of 1 cm per metre or an inclination 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 fitting must
be directed in the direction of fl ow.
• If the exhaust air pipeline is routed though cool rooms, loft s etc. there can 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.
