EcoFlex flexible duct is designed for HVAC applications that requires a stronger duct construction due to higher air pressure. It is specifically designed for thermal and acoustical insulation for HVAC applications. It is used in heating, ventilation and air conditioning to deliver and remove air.



  • APPLICATION
    Available either in plain or pre-insulated form, it is designed for use in all pressure cooling and heating systems. It is used in either supply or return sections: for branch ducts and branch connections to or between mixing units, induction connections to or between units, induction units, control or terminal units and diffusion devices, including light troffers. It provides economical means for handling misalignment between systems components and ducting around obstacles where fabricated and fitted ducts are difficult and costly to install. ECOFLEX is equally suitable for new jobs or retrofit work and is especially useful when making systems extensions or for changing zones, now or in the future

    Can be used in applications where internal air temperatures do not exceed ºC
