The Internal Rings reduces inflation "popping" in the textile duct caused by the initial air handling unit start-up. This reduces wear and tear of both suspension and textile duct system and thereby extends the longevity of the installed solution.
At the same time, the Internal Rings keeps the textile duct looking inflated even when the fan has been turned off.
The Internal Rings concept consists of 3mm and 4mm stainless steel rings placed each 500mm or 1000mm.
They are fixed with velcro straps for easy removal, should maintenance/washing be necessary.
Available in diameters from Ø200mm to $900mm.
Internal Rings for ducts to Ø500mm are already installed in the duct.
For bigger diameters, the Internal Rings are placed in a separate box and need to be installed by the customer.
