Note
■ The actual air flow rates that the
Vitovent can achieve are subject to the
pressure drop of the duct system and
that of the filters (filter class).
■ The speed of both fans is automati-
cally adapted to maintain the selected
air flow rate irrespective of the level of
filter contamination.
Duct system (flat) metal: Pre-selecting the supply/extract air
apertures
You will need the following design
details:
■ Pressure drop for the section
■ Air flow rates for the section
These details enable the determination
and pre-selection of the required aper-
ture sizes for the supply air and extract
air apertures using the relevant dia-
grams.
