The Trotec TFV Pro Duct Cap Set - 8x50mm allows for enhanced flexibility when using the TFV Pro 1 radial fan, expanding its functionality to work with multiple smaller hoses. This set includes adapters that enable the connection of 8 hoses, each with a diameter of 50 mm, making it ideal for targeted drying or ventilation tasks in confined spaces or areas that require more precise airflow management.
