Radial duct fan VK 00, 780m3 / h is designed for ventilation of medium and large non-residential spaces. The maintenance-free ABS plastic fan takes a good look and quiet performance. The built-in thermostat will simplify the ventilation of your rooms. Set the required temperature manually directly on the fan. If the temperature rises by 2 degrees, the engine will start to work faster. When the room cools down, it switches to a lower speed.
