YOUR CANOPY HOOD
Extraction systems
Depending on the type, the cooker hoods can
be connected in one of two ways:
1. To a duct. The cooking vapours extracted by suction are carried
outside, once the grease particles have been filtered. This is the
best method.
2. Recirculation hood. When the hood is connected as a recirculation
hood, the grease particles and odour in the extracted vapours are
filtered.
The extracted air is not carried outside but recirculates in the
kitchen. In this case you must have a carbon filter fitted.
Attention! The carbon filter needs to be ordered separately.
