KWL fan unit ego with heat recovery for functional spaces (V = up to 45 m³/h)

The ego is a heat recovery device that is primarily intended for functional rooms, such as bathrooms and kitchens. Paired operation is not necessary, as the ego autonomously ensures supply and exhaust air with heat recovery. At peak times, in the evenings for instance, it also has an exhaust air mode for rapid extraction of odours and moisture. The ego features two fans that are constantly working in opposite directions, and guarantee simultaneous supply and exhaust air. The storage brick sits in the middle of the air flow of two EC motors. Thanks to the reversing air flow generated by the targeted directional change of the fans, the ceramic becomes charged with the heat energy from the ambient air, and emits it into the outside air.
