Hi everyone I am building a laminar flow hood and I need some help. I have decided that I am going to use a 24" x 24" HEPA filter in my hood and I was wondering if it would be better to use a 11.5" deep HEPA or a 6"deep HEPA filter?
This is a link to the same 11.5" deep one that I might use http://www.grainger.com/Grainger/wwg/search.shtml?searchQuery=2dxn8&op=search&Ntt=2dxn8&N=0&sst=subset
Also, I need help with figuring out the size of a blower assembly I need to buy, and I know I need to get this right! If you look at the link for the 11.5" HEPA filter it says that It has a "Initial Resistance (In. WC) of 1.00" and a "Final Recommended Resistance (In.) of 2.00". How would I size for that?
I am thinking of using something like the filter at this link for my prefilter.
Last of all for anyone that has ever built a laminar flow hood, I would like to know if there is any thing that you regret not doing while building your hood or things that you wish you had done now that you have built your hood? Please let me know so I can hopefully avoid the regrets.
Thank you all for helping.
