I have a question, I have 4 rooms which have tanning beds. Obviously these rooms get hot, we are adding AC to help but was told to look into installing an exhaust system. I am pretty handy and should be able to install myself but I am sure the best way to go about it so it will make a difference. The rooms are all in line and the last room also has a 12x12 opening which I can exhaust out through. In researching I was thinking about 8in ducts through each room with vents for each room. Then possibly at the exhaust point put a high output fan do draw out the heat. Concern with that is not getting enough draw out of the last room and noise. I also looked at the same setup but instead of one exhaust fan, putting an vent tube with inline fan in each room. With back flow prevention between each room. Concern there would be those fans are not strong enought to draw out much heat.....any thoughts? I'm also trying to keep the costs low.

Be aware that to get air out there has to be a way to get air into the room as well. The rooms don't manufacture air inside to send out, you need a source of air to replace the air that leaves.

Yes, you really have to find out the MAKE and MODEL to get good answers. There IS more than one machine made.

That I understand, would I not get enough intake from ac being pumped in that is drawing from the exterior, plus it is a business so the door is always opening/closing

AC air isn't pumped in, unless there is a specific amount of fresh air pumped in due to occupancy codes during design. AC doesn't ordinarily introduce air, it exchanges heat from the air inside to the air outside through a machine, an AC doesn't exchange air, it exchanges heat. It would be too expensive to cool incoming air to cool the rooms.

To cut costs, you either introduce outside air in an intake to send the hot air out and exhaust, or you use AC to cool the air that remains inside.

In the situation of a tanning bed, the customers expect to be a bit warm so moving air alone MIGHT be sufficient, though it could make staff that stays in there uncomfortable on hot days.

You might consider one air conditioned reception room and separate ventilated tanning rooms.
