Thanks for the feedback brother. That was a section of the Ventilation Principles and Practices Class. I attached a file the full 3 hour class here please use and share at will. Without others providing me their material and message I would have nothing to give to you. All the videos referred to in this document are available on this site in videos or on my page. You can email me with any questions or for a full powerpoint. FDIC%20ventilation%20principles%20and%20practices.pdf
