DA 2900 ceiling extractor
Planning notes
Ceiling extractor ventilation technology
information
Extraction properties depend on various
criteria. A key criteria is the distance
between cooker hood and hob.
The optimum distance between hob and
ceiling extractor is 700 – 1300 mm. It
should be noted that vapours mix with air
as they rise. This can have a negative
influence on vapours. The bigger the gap,
the less grease reaches the ceiling
extractor. If hobs are used which improve
the transportation of vapours (hot air) to
cooker hood, grease separation in the
cooker hood is better too.
Air throughput on the DA 2900 of approx.
650 m
3
/h in Intensive is sufficient for a
kitchen with a floor area of approximately
20 m
2
and an optimum ceiling height. In a
kitchen of this size, 13-fold air
displacement is achieved. This means that
the air in the kitchen is displaced 13 times
per hour. Please note that grease not
immediately extracted during cooking may
stick to kitchen cabinets and cannot be
removed even with a high air displacement
rate. In cases of open-plan kitchens we
recommend to plan and evaluate the
kitchen space. Light vapour components
such as odour, moisture and smoke are
just as effectively extracted with a Miele
decor cooker hood.
