Cooker hood - Thermex Airslim

If you want the cooker hood to extract air via the ventilation unit, Nilan can supply a Thermex Airslim cooker hood for installation in a top cupboard. 

The cooker hood has no motor but is connected up to the ventilation unit. When extraction is required, you turn on the cooker hood. It then sends a signal to the ventilation unit which increases air extraction in order to achieve a high enough volume.  At the same time the supply air is increased to ensure balance in the ventilation process and to prevent negative pressure in the dwelling. 

It can be necessary to connect up an EM-box or a DTBU damper. It will regulate the extract air by ensuring that the cooker hood extracts as much air as possible when required.
