In the event of a fire or a high concentration of CO gas, the technology of the flue gas extraction fan system is based on the tunnel effect, causing the air to flow at a speed high enough to 'sweep' the ventilated surface. With this technology, there is no need to use a duct system, thus reducing the cost of installation work and installation materials.
In the event of a fire, flow fans prevent smoke from spreading throughout the room. Smoke is blown to one side of the room. This makes it easier for people to evacuate and for firefighters to find a fire. Outside the fire, flow fans operate to remove CO emissions. At higher than permissible CO concentrations, the CO sensor is activated and the flow fans start.
The big advantage is that this ventilation system is very economical, uses little electricity.
