We have a withdrawal well the hood, the date from outside with a plastic-return flap and a Außenjalusie (a component, also of Compair) was provided. Due to structural measures, we could no longer use as this component. Since the plastic lid was broken, I bought this return flap. I have so far a comparison between the flap of plastic and metal. Prospective I would always advise to this metal. The flap acts more stable. In the plastic flap, there have been folding noises (wind at the valve leaflets are already moving times, the springs for the collapse are very smooth), which does not exist at this flap so. Here a rubber is inserted, so that there is only a barely audible noise muffled folding. Otherwise, I hope that the hold (at the removed plastic flap already defective) Rückholfederchen here a little longer. Make anyway a good impression.
General: in a hood I would always advise to an air evacuation to the outside, and then use a flap so that it does not go into it's raining and not lose heat. Hoods that emit the air back into the interior, distribute the fine fat residues, which can not be filtered out, and certainly throughout the interior. Allen Kitchen farmers success
