Thermobox 150 Wall sleeve, black

Designed for cooker hoods with atmosphere connection

When the cooker hood is not working, this back draft damper stop the unwanted draft and save you valuable energy.

The COMPAIR® flow THERMOBOX 150 heat backflow damper is suitable for retrofitting existing wall boxes from the Naber® range. If the exhaust air is discharged via the roof, vertical installation is also possible. The blower door certified non-return flap scores with technical innovations such as heat-insulating reflection layers and a magnetic closing mechanism.

A predefined opening pressure of the exhaust air prevents rattling, with complete opening already occurring at a low volume flow. When the cooker bonnet is switched off, the heat retention system closes automatically to prevent energy loss due to cold air entering. Thanks to a shape that is optimally adapted to the pipe, retrofitting is extremely simple.

Heat retention system THERMOBOX for retrofitting of existing Naber® wall conducts and suitable for vertical installation (exhaust air outlet via the roof).
