Application

螺旋桨屋顶通风机费效比高，适用于商用建筑物的通风和许多工业建筑物的排风。根据各类使用要求，可选择皮带驱动型和直接驱动型，铸铝可调叶片或钢制固定叶片。

The TUD Upblast Tubeaxial Roof Ventilator provides cost effective, general-purpose ventilation for commercial buildings. The TUD includes a heavy-duty, galvanized steel stack cap with butterfly dampers to discharge air upward and prevent recirculation into the building. A splash guard located over the damper pivot area protects against rain entry.
