How can I simulate a fan inside a fluid domain?

Hi everyone.
Inside my fluid domain I'm trying to put a a surface or a volume to simulate a fan in which the air flow starts (fan) and another volume in which the air flow lasts (aspirator). Like an 'inlet' and 'outlet' but these two volumes are inside of the air domain so they come as interior BC. How can I simulate the fan and the aspirator? I would like to let the air pass from the fan to the aspirator.
Thanks in advance.

please check fan boundary condition in help.

I've read the fan boundary condition in the user's guide but nothing happens when I put these settings in the fan settings. I've set only the min and max velocity magnitude.

your min and max has very small difference.

I did as you say but the fan flow is very little.

 

This is the velocity contour

As you can see in this picture, the streamline is too little. I tried to put a fan where the streamlines begin and to get out from the building as the red indicator.
