The lossless Weibel wall box - the long missing "both-than-als-solution". Conventional exhaust grilles only decorate the permanently open hole in the house wall. Around the clock, expensive energy escapes here, even though the extractor hood is off. The kitchen cools so much that you cannot heat against it. But dispensing with the hole does not help. This is proven by the recirculation technology with all its disadvantages. The hole is needed – odours, grease and moisture must come out! This is especially important today. Because especially heavily insulated, airtight buildings require highly efficient ventilation so that no mould can occur. But when not in use, the heat should also remain in the house. So far, there has been no convincing solution. Thats why the lossless Weibel wall box was developed – uncompromisingly consistent. It offers "both and": when too, then properly - airtight and heat-insulated and when on, then right on - 100% ventilation efficiency because no component brakes the airflow. With its own drive, it opens automatically only when the cooker hood is switched on. When closed, it impresses with the best thermal insulation thanks to its unique multi-chamber construction. It can be used without any adapter both in new construction and in retrofitting with any pipe (up to D = 160) and with any extractor hood. Thanks to variable control options, it can also be used for tumble dryers, fireplace supply air openings, etc. (www.abluft-tuning.de)
