“Centrifugal Roof-Mounted Fan”

AC External Motor-Rotor Centrifugal Backward Curve Roof-Mounted Fans are industrial ventilation fans designed for commercial and industrial buildings.
These fans are typically mounted on the roof of a building and are used to exhaust hot or contaminated air from the interior of the building.
The fan consists of a motor and rotor assembly enclosed in a housing. The motor powers the rotor, which spins at high speeds to generate a large airflow volume.
The accommodation is designed to direct the airflow in a specific direction, typically out of the building through a duct or vent.
One of the critical features of these fans is that they use a backward curve design for the rotor.
This means that the rotor blades are curved in the opposite direction of the rotation, which helps to increase the fan’s efficiency.
As a result, these fans can move a large volume of air with relatively low energy consumption.
Another essential feature of these fans is that they are weather-resistant and are designed to withstand harsh conditions on a rooftop.
This includes exposure to high winds, rain, and extreme temperatures. Additionally, the fans are designed to be easy to install and maintain.
In summary, AC External Motor-Rotor Centrifugal Backward Curve Roof-Mounted Fans are a type of ventilation fan designed to be mounted on the roof of a building.
They use a backward curve design to increase efficiency and are weather-resistant and easy to install and maintain.
They are commonly used to exhaust hot or contaminated air from the interior of the building.
