The main feature of opening slope smoke vents is that they can ventilate industrial plants 24 hours a day. This type of smoke vent rooflight is more common in southern my country. Because of the climate characteristics of the southern region, the winter is generally mild and humid, so there is no need to heat the plant, and there is no need to install the opening and closing valve plate.

The purpose of installing the opening and closing valve plate is to be able to freely adjust whether the plant area needs to be ventilated or insulated. On the other hand, the slope natural ventilation system is not equipped with the opening and closing valve plate, so it is cheaper than the opening and closing ridge ventilator in terms of cost, and it is a more economical and practical type of smoke vents.

Another obvious feature of the slope smoke vent rooflight arranged in a downhill position is that the general throat is relatively small, so the load is also lighter. Such a smoke vent rooflight is installed on the roof relative to the large throat air building.
