Why is the total pressure of the general centrifugal fans used behind the absorption tower in fine chemical industries 2000 Pa?

I would appreciate it if the experts here could explain why the total pressure of the general-purpose centrifugal fans used behind the absorption tower in fine chemical industries is 2000 Pa?
This is because in the production process of fine chemicals, the exhaust gas must be purified after passing through the absorption tower; materials such as adsorbents are generally used for adsorption and filtration. A general-purpose centrifugal fan is a device used to provide the required air flow; in this process, factors such as resistance and friction must be overcome, which means that the total pressure required is around 2000 Pa. Of course, the specific design parameters are also influenced by various factors such as different process requirements and equipment performance. .
Why not 3000 Pa? Is there any basis for that?
It is necessary to calculate the pressure drop in the process flow, as well as the exit flow velocity
