Flexible ducting connector with male ends for joining two spiral or plain round ducts. Most commonly used for reducing vibration caused by ventilation and heat recovery units as well as duct fans. Flexible ducting connector eliminates the transmission of vibration to the ducting system- consequently improving the acoustic performance of the installation. It is made of AMT flexible duct connector (a joint consisting of a layer of fabric and two strips of sheet metal on both sides), which is available in different dimensions and materials also with increased temperature resistance.
