With the continuous development of modern industrial plant construction, the use of smoke vents with ventilation, lighting and smoke exhaust functions has become more and more widely used. However, there are various types of smoke exhaust ventilator, and some users do not know the difference between various models. Now Mcwell will introduce the difference.

From the name, it can be seen that the opening natural ventilator cannot be closed, and the amount of ventilation and smoke cannot be controlled. It is not equipped with an electric valve plate, which can realize all-weather ventilation for the workshop. Since the opening skylight cannot be closed, it has no thermal insulation function. Therefore, this type of roof smoke exhaust ventilator is mainly used in the south without thermal insulation requirements and in factories without the need to control the ventilation and smoke emission.

It can be seen from the literal meaning that the electric opening and closing type ventilation skylight can be opened and closed. The roof smoke exhaust skylight is equipped with an electric valve plate, which can control the opening and closing of the ventilation skylight through the valve plate. When the temperature outside the workshop is too low in winter, or in extreme weather such as strong wind, heavy rain, and heavy snow, the valve plate can be closed to keep the workshop warm; provide a comfortable working environment for the factory.

Both types of factory smoke vent rooflight have the functions of ventilation, lighting, fire control and smoke exhaust. Since the open-close type ventilation skylight is additionally equipped with an electric valve plate, the price of the open-close type skylight is higher than that of the open type under the same material configuration. The price of ventilation skylights.
