The Kompass roof hood is designed specifically for the intake of outdoor air on roofs. The unique construction of the Kompass prevents water drops and snow penetrating into the duct system.
The profile and chamber construction is based on ø8 mm holes with large openings on the top and the bottom of the product, which means non-freezing construction. There is a large space for collecting and storing the snow on the lower part of the Kompass. The waster resistance of the Kompass is almost 100% with the recommended maximum air flow.
