Groupe Brandt HCL90W is a versatile kitchen appliance that can be used for both ducting and filtering. In ducting mode, cooking fumes and odors are expelled to the outside through a ceiling or wall vent. In filtering mode, the air is purified by an activated charcoal filter and recirculated back into the kitchen. The hood features three speed settings to adjust the extraction power according to cooking intensity, as well as a light switch for illumination while cooking. Installation can be done as a wall-mounted or under-cabinet unit, depending on your kitchen layout.
