Flexible duct connector made of two FLS steel flanges interconnected by ILA flexible connector. Most commonly used for reducing vibration caused by ventilation and heat recovery units as well as duct fans. Flexible duct 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.
