Schellenberg Universal window fan starter set

With the help of continuous air exchange, they reduce relative humidity and pollutants in the indoor air. The continuous fine ventilation, prevents the formation of mold on window sills and gives damp walls back their original insulating properties. Due to the improved indoor air, less energy is needed to heat the rooms, which also allows you to save on heating and energy costs.Universal window ventilators are attached to the sash of a plastic window with a few simple steps. To do this, you need to remove part of the rubber seal. The accessories required for mounting are included in the scope of delivery. The universal window ventilators do not require a power connection and are operated purely mechanically. Their mode of operation is comparable to that of more cost-intensive supply or exhaust air systems. For every 10 m² of living space, install one window ventilator on each side of the facade to enable cross-ventilation. Even a small door gap of 7 mm under the closed room door ensures cross-room air circulation. With a slider on the window ventilator, the air supply can be manually interrupted at any time.
