How about one of these to shoot the hot air out?

Would the following plan work?
- 8 inch 720 CFM fan booster to push air outside (the run is about 20 feet straight to outside). I will put this vent right above the mining rigs to draw out the most heat.
- Put the door on the room so its about 90% sealed and only a small amount of air will get in under the door
- 8 inch fan with booster (same booster as above) on the other side of the room to bring in basement temp air and in the winder times it will bring in filtered cold air from outside


So will have two vents in this room.
- One to suck hot air out of the room right off the rigs
- One to push in cooler air from basement / filtered outside air.


Thanks for your advice!

Long story short looking for a way to vent air out and also bring air in without running two vents. Also looking at pros and cons of just venting out vs venting out and in. Please take a look at my video. Thanks!
