As a specialist in high end kitchen ventilation we offer the best components and advise, based on the latest developments. We have a perfect solution for each situation, with a matching range of external motors in different capacities, like inline, flat or tiles roof and external wall motors. For an efficient and noise-reducing connection of extractor and motor or outlet, you can choose [or ask our advise] from a round flexible duct, to the extra flat HR+ duct components in any diameter you can think of. Specifically designed for central ventilation systems [CEV] with or without heat recovery [HRV], we offer the optional, patented CMVR® system. As a better alternative to a recirculation or motorless extractor, this energy-saving system can be ordered on any ABK InnoVent extractor, ask our sales department for a clear explanation.
