Three centrifugal fans with different outlet pressures entering the same equipment will have any impact on the pressure drop and flow rate? !
Thread Content
There are three fans, two of them are the same, with an outlet pressure of 6KPa, and the other one has an outlet pressure of 2KPa. Three fans run at the same time, adding one piece of equipment. Will the first two typhoons suppress the third turbine? What impact will it have on its pressure drop and air volume? Thanks. . See picture:
personal opinion: This should increase the outlet pressure of the third station and reduce the air volume.

It depends on how high the pressure of the storage tank is controlled. If it is lower than 2kpa, all three fans can work normally. If it is greater than 2kpa, the 2kpa fan will be severely reduced. If the outlet of the 2kpa fan is closed and it cannot reach 6kpa, then when the pressure of the storage tank is controlled at 6kpa, the 2kpa fan will reverse the air.
It's not a storage tank, it's an adsorber. The pressure drop is about 1KPa. It's no problem for a 2KPa fan to work normally, but the flow rate may be affected. .
That is the case below 2kpa, it can work normally without any problem!
I feel like that small pressure head blower will suppress the pressure.
Is there any problem with connecting like this? Is it possible to connect the inlets of the three fans to the storage tank?
Under such working conditions, it is not 2kpa that has a problem, but 6kpa that has a big impact, right?
