How to set the boundary condition of a sealed room

I am now making a flow simulation project of a factory.

The factory has some extraction air ducts and intake fans. Also, there is no opening (e.g door or window) to the environment except the intake fan

I set the boundary condition of the extraction air duct by outlet volume flow.

I know that the setting of the boundary condition (inlet or outlet) should included one "pressure setting" in order to start the simulation

But, I don't know how to set the boundary condition for the fans.

Also, I only have the following data for the fan:

Flow Volume,Rotating Speed ,Size and Power.

It would be so kind of you guys to help me. THANKS
