The ridge ventilator is installed on the roof of the building and used for indoor ventilation of the building (part of the building is also used for lighting). The streamlined natural ventilator is a non-standard customized product, and the customer needs to provide specific design drawings, so that the smoke vent manufacturers can customize the specifications, dimensions, and materials of the smoke vent skylights according to the design drawings. In this process, the throat size is extremely critical, and the size of the reserved throat has a significant impact on the ventilation volume.

If our newly-built industrial plant needs a customized ridge ventilator, when the steel structure company completes the construction of the plant, a ventilation hole will be reserved on the building roof, and the throat of our streamlined natural ventilator refers to the air building and roof reservation The width of the opening is equal, and its size determines the amount of ventilation.

The standard throat size of the smoke vent skylights refer to the national standard atlas of air building. Its size is generally within an adjustable range of 0.6m-9m. The larger throat size means the larger volume of the natural roof ventilation. The hourly ventilation is also greater, which is suitable for those industrial plants that require relatively high ventilation. Some factories do not have such high requirements for ventilation, so you can use a ridge ventilator with a relatively small throat size, which can reduce the cost of the enterprise, and can play the role of the ventilation building to a greater extent.
