The Optimum wall exhaust is constructed to prevent ice formation on the inner cover and the infiltration of weather. So there is no possibility of cold air into the interior of the house. Is lined with felt, the inner door is silent at all times. The structure made of galvanized steel, prevents perforation from rodents as seen sometimes on plastic valves. The mesh shaped in the same material as the structure makes the intrusion of birds or rodents can not inward while remaining easy to maintain. With a collar of 9Ã¢â‚¬â„¢Ã¢â‚¬â„¢, the valve does not need an extension that would increase the number of joints and prevents any obstruction of the device. The opening angle down, in turn, allows an optimum air exhaust in any season while preventing lint and dirt from sticking to the wall.
