As a natural ventilation facility for industrial factory buildings, electric smoke exhaust ventilator has been selected by many business owners as a necessary facility for the roof. Business owners who choose smoke vent rooflight will select them according to their performance characteristics. Among them, ventilation performance is a key factor considered by many owners.

1. Factors which affect the ventilation performance of electric smoke exhaust ventilator

The geometric dimensions of the electric smoke hatch skylight, that is, the total width and the total height, determine the effective ventilation area and effective exhaust height of the smoke exhaust skylight, which greatly affects the effective ventilation volume of the electric smoke vent system on the roof.

2. Reasons for poor ventilation performance

The geometric dimensions of the smoke vent rooflight of the general factories are small, and the effective ventilation area and exhaust height are not enough, so the ventilation volume is small. In addition, the unreasonable internal structure will also result in insufficient effective ventilation area. The effective ventilation volume taken is just a reference to the general value of the industry, which lacks basis. The poor ventilation performance of the automatic opening vent is often due to the inaccurate reference ventilation volume and insufficient effective ventilation area.

3. The excellent ventilation performance of Mcwell's smoke hatch skylight

The geometric dimensions of Mcwell's electric smoke exhaust ventilator is set in accordance with the standard to ensure a large effective ventilation area and effective exhaust height to meet the requirements to ensure a large effective ventilation volume and achieve better ventilation performance after calculation. In addition, the internal structure of the smoke hatch skylight strives to be reasonable to ensure that the effective ventilation area is larger. At the same time, the product is sent to a professional authority for testing, and the measured actual ventilation rate is used as the effective ventilation rate reference, so it can ensure the accuracy of the ventilation rate in actual use and ensure good ventilation performance.
