To ensure optimal performance and safety with your VETUS VENT178B2 Extractor Fan, your ventilation duct must adhere to specific criteria. Firstly, the internal diameter of the ducting needs to be 178 mm (7 inches) to match the fan's specifications. Secondly, the material should be smooth internally and able to withstand temperatures up to 70 degrees Celsius (158 degrees Fahrenheit). The ducting must also be resistant to oil, water, and fuel, as it will likely be used in an engine room environment. Furthermore, the duct should be designed to handle both under and over-pressure conditions, which is crucial for maintaining efficient airflow. Finally, for the best results, keep the duct run short with as few bends as possible, and use large bend radii. Securely install the duct with stainless steel clamps to prevent any slippage. By paying attention to these details, you can be confident that your ventilation system is correctly configured to work with the VETUS VENT178B2 Extractor Fan.
