My current ventilation system is really inadequate......I've been reading thru all the ventilation threads for the last few months now and I want to make sure I'm (or my husband rather) setting up my ventilation system correctly but I still have several questions. I've attached a picture of Lenora's system that I really like but I'm going to do some size modifications which are highlighted in red. I've also attached a link with specs and picture of a Grainger squirrel cage fan that I would like to purchase but need some clarification on before I spend the $200 on it.
My questions are:
1. Based on my numbers (28 x 24 / 144 * 125 = 583), I need a min of 583 cfm fan. Do ya'll agree?
2.
Grainger link.......The exhaust part of this fan is rectangular, can I put an 'adaptor' on it that turns it into a circular 8 inch exhaust? (I hope that made sense!)
3. Concerning this squirrel fan, is the 6 inch intake adequate? I am planning on using 8 inch exhaust ducts, non flex of course.
4. What is this thing circled in green? It looks like a mounting area but I'm not really sure because this fan model is a little different from the other fans on the Grainger website.
5. Some fans have an 'open' motor design which requires a separate plenum box built. Is this one of those fans?
6. Is my hood big enough? I am using a Cricket with a 5 LPM oxycon.
7. Am I asking too many questions?
I want to thank everyone for their help in advance!!!!
