The question should be more accurate. You have got a centrifugal air blower driven by a Universal AC-motor from normal mains supply. How will the typical flow/pressure characteristics look like? A Universal AC-motor got variable speed. A typical example of such an air blower is the motor of a vacuum cleaner.
The same kind of air blowers are used for many purposes like filling air madrassas, airtracks for gymnastics or paddle boards recreational use. Blowers can also be used to blow away leaves in autumn.
I got the characteristics from a Chinese manufacturer of a motor designed for a vacuum cleaner and it looks like this:
It seems that the characteristic is quite linear.
Typically manufacturers of such cheap air blowers do not provide such characteristics, but perhaps only max flow and max pressure.
I should like to know, if you have got other examples of the flow/pressure characteristic for such a blower. It might confirm my pressent assumption, that the characteristic is close to be linear.
