Frequently Asked Questions

  • How many rooms can one radial ducting manifold serve?

    The number of rooms depends on the number of manifold ports and the airflow required at each valve. Some rooms may require more than one duct connection, so the manifold should be selected as part of the complete system design.

  • What is the maximum recommended length for semi-rigid radial ducting?

    There is no universal maximum length. Suitable run length depends on duct diameter, airflow, bends, pressure loss and manufacturer guidance.

  • Is semi-rigid radial ducting suitable for DIY installation?

    Semi-rigid ducting can be easier to route than traditional rigid branch systems because individual ducts run from the manifold to each room.
