  1. Uses<\/strong><\/li>\n<\/ol>\n
      \n
    • Collect or distribute air from fans, AHUs, FCUs or central air conditioning units.<\/li>\n
    • Air is led through air vents, flexible air ducts or round air ducts to air supply locations in the room.<\/li>\n
    • Help Evenly distributed air flow<\/strong> and reduce noise before the air exits the vent.<\/li>\n<\/ul>\n
        \n
      1. Structure<\/strong><\/li>\n<\/ol>\n
          \n
        • Box body<\/strong>: rectangular or square, combination round neck<\/strong> (collar) for connecting round ducts or flexible pipes.<\/li>\n
        • Round neck<\/strong>: rounded edges or fitted with airtight gaskets, secured with rivets or spot welding.<\/li>\n
        • Input\/Output<\/strong>: can be square flange (TDC\/TDF) or open face for direct connection to fan\/air vent.<\/li>\n<\/ul>\n
            \n
          1. Material<\/strong><\/li>\n<\/ol>\n
              \n
