Roof smoke vent is also called ventilation buildings, which is mainly used for natural ventilation and lighting of factories. They are economical, environmentally friendly, energy-saving and consumption-reducing ventilation facilities. So what are the types of roof smoke ventilator? Mcwell will briefly introduce the classification of smoke vent rooflight and their different characteristics.

Roof smoke vent can be divided into roof louver vent and streamlined natural ventilator according to their appearance characteristics. Refer to the industry national standard 05J621-3 "Roof Smoke Vent" and 11CJ33 "Smoke Ventilator". The models of low-profile ventilator are TC11/12 and MCW1/2. The skylight is characterized by low window height (generally no more than 650mm), light weight, strong wind resistance, strong applicability, relatively economical weather, and can reduce user input.

The streamlined natural ventilator, as its name implies, is named for its streamlined appearance. The overall design is streamlined and arc-shaped, so that the external wind pressure is reduced to ensure the strength of the roof vents, and the internal streamline can improve ventilation efficiency.

Ridge ventilator is divided into two types according to different specifications and sizes: one is frame-type streamlined ventilation skylights. This type of skylight has a small throat size, generally no more than 1000mm. The frame is usually pressed with galvanized sheet and does not need The installation base is arranged downhill. For details, please refer to the MCW6/7 type ventilation skylight in the national standard 11CJ33; the second is the welding frame type streamline ventilation skylight, the throat size is generally above 1200mm, and the roof ridge and downhill layout can be used. The frame is made of section steel by bending and welding, the frame is fixedly welded or bolted to the base, and the outer guard plate is provided with large ventilation and high efficiency. Refer to the national standard atlas for selection, the commonly used models for streamlined ventilation skylights are TC3/5, MCW4/5 and HZT series skylights.
