Specifications:

To make the right selection, one must clearly identify the specifications – General Information as well as In-Depth Requirements, if necessary.

General information includes-

Application
Type of gas being moved
Number of systems
Fans per system
Type of fan required: axial, centrifugal, mixed flow, or turbo
Fan arrangement and control
Expectations regarding the equipment life
Ancillary items to be supplied by the fan manufacturer
Besides that the end-user must derive the following conditions the fan or blower will be subjected to:

1. The required airflow: It is rated in cubic feet of air per minute (CFM) or in metric equivalent, it is rated in cubic meters per hour (M³HR).

3. The static pressure through the system: Rated in static pressure water gauge (SPWG) or in metric equivalent, it is rated in Pascal’s (Pa). SPWG or Pa is the resistance to flow, or friction, caused by the air moving through the system.

4. The ambient air temperature outside the fan

5. The airflow conditions through the fan

Maximum operating temperature?
Clean or dirty air?
6. The altitude the fan will be operating at.

Conclusion: To put it simply, the high temp industrial fan selection will be based on the type of fan that is best suited by performance, design, and features that best meet those conditions.
