      just a question: how many air changes for hour you do in this huge cleanroom? The cleanroom is ISO 3 - Class 1?

      Class-10,000. It circulates ~1 million cubic feet of air every minute through 9,000 sq feet of HEPA filters!

          you need an airplane engine to move this amount of fluid through a filter wide as more then 3 tennis fields!
