Factory Wholesale Direct High Efficiency L Roof Ventilation Top Fan

The ventilators use the heat convection of air caused by natural wind force and indoor and outdoor temperature difference to push the turbine to rotate so as to use centrifugal force and negative pressure effect to expel the indoor unfresh hot air.
The roof fan is installed on the roof for ventilation. Due to the particularity of the installation environment, the material and structure of the fan are special. The roof fan is equipped with a device to prevent air backflow after shutdown. Due to the high-speed rotation of the fan under the action of hot pressure, the wind speed in the air duct increases a lot, and the fan reverse is very unfavorable to the start of the motor, which may be damaged due to excessive starting current.

The roof fan should be designed with reliable performance of rain proof, snow proof and sand proof. Snow and sand are not like rain, because snow and sand will not only enter the fan from the upper part, but also enter the fan from the lower part when the outdoor wind speed reaches a certain intensity.

 

Roof turbo ventilator is mainly used in the ventilation of large plant, warehouse, stadium, animal farm, business site, high-rise building, residential building, etc.
