With an extractor system as a downdraft and hob ventilator, the exhaust air duct runs in the floor structure or in the base cabinet. So what could be more reasonable than to install the wall box just above the ground? This reduces the installation effort and keeps the cable paths short.

The elegant COMPAIR^® Turbo external blind is made of weatherproof stainless steel and is mounted at least 200 millimeters above the top edge of the ground. With its special geometry of blades, it forms a free jet, similar to the jet engine of a jet aircraft. The outflowing air entrains the ambient air. Thus the vapours are reliably and cleanly conducted away from the house facade.

The Turbo wall box can be supplied with a round connection piece in 150 mm diameter or as Turbo flow with a rectangular connection 227 x 94 mm for the Naber flat ducts made of plastic or metal. Thanks to the THERMOBOX, these wall boxes from Naber also fulfil the highest requirements for airtightness and energy efficiency.
