Since our humble beginnings more than 40 years ago, Genvex has been supplying both homes and businesses with ventilation systems of the highest quality. We started out as a small division of the company V.M Christensen, but have since then evolved into a global, market leading brand with a wide range of innovative products and indoor climate solutions.

From our production facilities in Haderslev, we work continuously to develop new products and optimize existing ones. Our goals are simple: we want to deliver ventilation solutions that meets the demands of the market, contribute to a sustainable future and deliver fresh, clean air for all types of homes.
