100mm Heat Recovery Kit with Wall Switch. The device is equipped with a regenerator that accumulates the thermal energy of the air leaving the room and heats the fresh air entering the room, thus ensuring minimal heat loss. The device is designed for continuous operation.The process consists of two stages, 70 seconds each. The first stage - the fan works on extraction, removing the exhaust air from the room to the outdoors.
In this process, warm air from the room passes through a heat exchanger - a ceramic mesh element and heats it up. The second stage - after the specified time has elapsed, the fan automatically switches to the fresh air supply.And here the previously mentioned ceramic mesh element plays the main role. Fresh air from the outside, passing through a preheated heat exchanger, gives off heat to the air which is supplied to the room already warmed up. Consumption: 1st gear - 1.5W / 2nd gear 2W. Max Flow Rate: 1st gear - 20m3/h / 2nd gear 24m3/h. This item is in the category "Home, Furniture & DIY\Heating, Cooling & Air\Air Quality & Fans\Extractor Fans".
