Would this hepa filter/ inline fan work for a laminar flow hood setup

Good morning all, just a quick question.. I'm looking to build a nice sized flow hood and stumbled across this filter http://www.ebay.com/itm/301651896285 seems like it would work but I'm not even the closest to being experienced lol. I also have this fan http://www.htgsupply.com/products/growbright-8-inch-high-velocity-fan says 590cfm but I can't find any other info on the fan when it comes to how it works under pressure. So does anyone have any ideas on if these two items will be Allright to work together. Thanks

Go look up the math and see if they match. Youll have to ask the blower manufacturer for the chart that shows the CFM at different resistance then find the resistance of the filter then see if the blower will work or not.
I don't care if I sound like a dick but if you don't know how to build one and can't look up the easiest math in the world you don't need a hood.

Let me first off say yea you do sound like a dick second I diddent say I couldn't do the as you say easiest math in the world... I asked if anyone had any info on if those two items would match up...not that I couldn't do the damn math.. I just figured with the shroomery forums being one of the largest sites for mushroom myco that I would get a good answer not some half asset answer..and as I said the manufacturer does not specify the cfm under pressure.. but as you may already know as your reading this that this post is not going to go anywhere but down the drain seeing as how the first response to a simple 2 answer question turned up a response such as yours. Have a good day and I'll look elsewhere for answers. Good day sir

It was a great answer where not here to hold your hand we are here to help you grow mushrooms. 99.9% chance that a SAB is the right answer for you a anyway are you doing 100s of jars a week? Then you don't need a hood unless you just need overkill in your life. In that case pay someone to do it for you or figure it out.
I'd rather have you look it up and actually figure it out than me do all your work for you to find a chart and see if your shit matches up. Im not emailing a manufacturer for you 
Size of filter in sq feet So 12X24 is 1X2 feet or 2sq feet For each square foot 100cfm So 200cfm What's the resistance of the HEPA (usually 1.0" w.g.) Prefilter usually 0.2" w.g. 1.2" w.g. Get the chart for the blower find 1.2 w.g. see if it pushes at least 200cfm if it's over you'll have to throttle if it's under it won't work
Easy math. Multiplication and division
Do the work to see if they match up... Want me to call then for you? If you cant find the specs of a chart then that's what you'll have to do or find a different blower.
Make a still air box... Basic questions don't go in advanced mycology. So before you get all offended please read rules 
https://www.shroomery.org/13876/Still-Air-Boxes-Gloveboxes-and-Flowhoods-updated-2017
Flowhood is at the bottom of that page

Like I said do the work and research if you want one don't just go asking people if shit works together...

Like I said post going down the drain and just for your info I do about 45 large bags a week and I do have a damn still air box I'm just sick of using it and diddent want to spend the money on a fully built laminar hood figured I would build it myself. Just because I only post every once in awhile and have 9 post doesn't constitute that I should not post a question in advanced myco section about laminar flow hoods and filters seeing as how it is an advanced area for most. As you have already said SAB is not advanced.. but enough of this back and forth shit in have mushrooms to grow have a good day sir for mods please feel free to delete entire post as its really not helping the forum in any way.

It's easier to buy the filter you want and then get a motor that works
Find the motor's chart or email the manufacturer
 Should look like that. If you have a 0.8 HEPA then the blower will push 360cfm
360cfm = 3.6 sq ft since 100cfm per sq ft 16*32=512 square inches /144=3.555sq ft 3.555 sqft X 100cfm per sq ft = 355cfm So if you had a 16X32 HEPA that was 0.8 w.g that blower would work perfect.
Make sense?
