The Zehnder Roof Fan ComfoRoof MX Automatic 110 D is a robust and energy-efficient roof fan specifically designed for ventilation applications in commercial buildings, residences, and other environments where controlled airflows are essential. This model provides an efficient and reliable solution for ventilation in small to medium-sized installations.
The Zehnder Roof Fan ComfoRoof MX Automatic 110 D is the most comprehensive version, suitable for a flow rate of up to 1300 m³/h and features a 3-phase 400V/50Hz connection. There is also a variant with a 1-phase 230V connection. The fan is equipped with a 0-10V input for automatic speed control. Additionally, the system includes a clock program, Modbus support, and can be configured with a local web server for operation and monitoring. Pressure control is available to further optimize the system's performance. The roof fan can be combined with the insulated roof duct DOS G 330 or the roof duct DOS 330. Furthermore, the sound damper GDH-K 330 can be placed directly between the roof duct and the roof fan to minimize noise disturbance.
The ComfoRoof models are available with both a 1-phase 230V connection and a 3-phase 400V/50Hz connection. The D in the product name refers to the power supply voltage of 400V/50Hz. Air performance and sound levels are exactly the same for both versions; however, they differ in connection method and power consumption.
