Recirculated mode
A recirculated rangehood takes in vapours with the aid of a fan,
cleans them in various lters and returns them to the room after the
ltering process. In this way air circulation occurs within a closed
room. Recirculation rangehoods do not require any ducting to the
outside nor any wall openings. Due to this, installation is simpler
compared to vented rangehoods.
+ Simple installation
+ No building alterations necessary
+ In winter, heat stays in the room
+ Good performance parameters
– A large part of the moisture remains in the room.
As a consequence, rapid air exchange by means of opening
windows is necessary.
– NoSmell active charcoal lter needs to be replaced regularly.
– In summer, refrigerated / cooled air is warmed.
To vent or not to vent?
Vented mode
Rangehoods in vented mode also take in vapours via the fan and
lter them. In contrast to recirculation rangehoods, however, vented
or extraction rangehoods transport the ltered air via ducting out
of the kitchen. In order to direct the exhaust air outside, vented
rangehoods require a wall or roof outlet. All vented rangehoods are
connected to a ducting system that enables odours and moisture
to be carried outside. Ideally, because air is taken out of the room,
the kitchen needs simultaneous air intake such as through an open
window.
+ High air volume
+ Moisture is extracted
+ High eciency
+ No continual additional costs
+ Hot air is extracted and led to the outside, reducing the load of
the air-conditioning system
– Amount of air extracted and performance of the rangehood
dependent on the quality of the ducting set-up.
– Not able to be installed everywhere.
– Loss of heat during winter
Extracted air needs to
be replenished
