Simulating Fan in Ansys CFX

Hi,

I have this air fluid volume and I have created a face to specify an air velocity (because fans are positioned there).
However when I do this, Ansys thinks the air flow is bidirectional.

Any idea how I can prevent this? I need to specify it one direction. I have inlet and outlet defined as zero static pressure.

How else can I model this?

Thanks in advance!
