thanks for your reply's guys

i have brought in an evaporative ac to rated at 12000 cfm. I was able to turn off 3 ac's from 5 and the average temperature is around 65 degrees at 70% fan speed. problem this pulled alot of dust. i need to do a major cleanup + add filters for the fresh air.

I will upload some photo's of the setup soon and would like to hear your feedback.
