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.
