Fan Vents VK 125 Un - 355m3/h with a thermostat

Product detailed description

The plastic duct fan with a thermostat, VK 125 U, 355m³/h, is designed for ventilating smaller non-residential spaces. This maintenance-free ABS plastic fan stands out with its lightweight, quiet operation, and long lifespan. The built-in thermostat simplifies the ventilation of your rooms. You manually set the desired temperature directly on the fan. If the temperature increases by 2 degrees, the motor starts running faster. When the room cools down, it switches back to a lower speed.
