There are actually many different types of high-temperature fire-rated axial fans available on the market today.
When selecting a model, users may need to pay closer attention to these various products.
However, understanding the different types of high-temperature fire-rated axial fans in advance makes the selection process much easier.
To facilitate differentiation, they are classified based on their characteristics. When classifying rooftop high-temperature fire-rated axial fans, they can be categorized according to various criteria.
For example, they can be classified by rotation direction into two types: left-rotating rooftop fans and right-rotating rooftop fans.
In practice, this method can be used to distinguish them. Standing at one end of the fan, you can observe the rotation of the rooftop high-temperature fire-rated axial fan primarily by checking the propeller’s rotation direction.
Clockwise rotation indicates a clockwise-rotating unit, while counterclockwise rotation indicates a counterclockwise-rotating unit.
Additionally, high-temperature fire-rated axial fans for rooftops can be classified based on their inlet direction. Thus, they can be categorized into single-sided single-stage inlet units and single-sided two-stage inlet units.
Generally, under the same conditions, the air pressure generated by the latter must be twice that of the former.
However, there are many other methods for classifying types of high-temperature fire-rated axial fans.
For example, they can be distinguished based on name, model, rotation direction, transmission mode, and the location of the exhaust outlet.
