  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

            • Options: Stainless steel 304\/201<\/strong> or powder coated steel if high aesthetic requirements or corrosive environment.<\/li>\n
            • Surface can be insulation<\/strong> with glass wool or vulcanized rubber to reduce heat loss and noise.<\/li>\n<\/ul>\n
                \n
              1. Specifications \u2013 Dimensions<\/strong><\/li>\n<\/ol>\n
                  \n
                • Box size (W \u00d7 H \u00d7 L) according to design drawing or actual requirement.<\/li>\n
                • Number of round necks: 1\u20136 necks depending on needs.<\/li>\n
                • Round neck diameter (\u00d8): 100 \u2013 500 mm.<\/li>\n
                • Neck length: 50 \u2013 100 mm, with tube holder.<\/li>\n<\/ul>\n
                    \n
                  1. Processing<\/strong><\/li>\n<\/ol>\n
                      \n
                    • The box body is Pittsburgh seamed or spot welded, ensuring high air tightness.<\/li>\n
                    • Round neck is stamped and edged by specialized machine, ensuring even roundness and tight fit to the flexible air duct.<\/li>\n
                    • All joints are treated with sealant to prevent air leakage.<\/li>\n<\/ul>\n
                        \n
                      1. Application<\/strong><\/li>\n<\/ol>\n
                          \n
                        • HVAC System<\/strong>: cold air supply from central air conditioning.<\/li>\n
