Abstract (en)
[origin: EP3633284A1] A duct connection port (22) to be mounted to a heat exchange ventilator that is a ventilator for connection to a ventilation duct includes an outer hull and an inner hull (22h). The outer hull includes cylindrical parts (22b, 22c, and 22d) to be connected to ducts. The inner hull (22h) defines a passage for a ventilation air flow. The inner hull is disposed inside the cylindrical parts (22c, 22d) defining a part of the outer hull, and is spaced away from the cylindrical parts (22c and 22d). The cylindrical parts (22b, 22c, and 22d) defining the outer hull are integral with the inner hull (22h).
