The main principle of work of the ventilation device (fan) is the extraction of hot air from the heat source (fireplace) and redistributing it to all premises through heat pipes. A thermal sensor inside the device automatically turns the fan on and off, depending on the temperature of the heat source. Combining the heat source with the fan gives the effect of central heating and even greater comfort can be achieved using an electronic temperature controller. Using it the air flow and the pressure in the system can be controlled.

In order to achieve the best very important factor is that the fan is situated properly and connected properly to the air heating system.

The following fan models are produced, having air flow from 350 to 850m³/h.
