The volume of air that has to be extracted is spe-
cified in the Building Regulations. The volume of
air flowing into the home has to be in balance
with the extracted volume. The volume of air
extracted from and supplied to the home should,
in other words, be equal. The minimum air volu-
me per room is also determined by the Building
Regulations. The set volume of air is determined
based on achieving an optimum home climate
without wasting energy. The air intake and dis-
charge per room are not equal. The extraction
and intake grilles all have their own fixed posi-
tions and settings.
