Fan Vents VK 250 Un - 1080m3/h with a thermostat

Product detailed description

The VK 250 U duct fan, 1080m³/h, is made from durable and lightweight ABS plastic. This duct fan is ideal for air extraction in medium-sized office, commercial, or residential spaces, as well as industrial operations. The built-in thermostat simplifies the ventilation process. You manually set the desired temperature on the fan, and if the temperature rises by 2°C, the motor will automatically switch to a higher speed. When the room cools down, the fan switches back to a lower speed.
