I hope he's alright :frown:

I wonder if I stirred up anything in that thread of his...I put it in my hidden folder because I find it disgusting when people tell depressed people to go do some drugs to fix their (sometimes serious) emotional problems.

And this is exactly why you shouldn't assume it will be the same for someone who isn't you, like so many who haven't experienced losing a suicidal friend to "happy" drugs tend to do.

Anyways, I don't mean to threadjack, I just find it just pretty pathetic the general response around these parts to a disappearance of a regular member under those circumstances.

Hopefully he'll come back and tell me I'm a goof. Til then, I hope he's ok.

1. Find out the area of your filter by multiplying the width and the hight in feet (for instance the smallest reasonably usable filter would be 2ft x 1ft)

2ft x 1ft = 2 ft2

2. Multiply the required air speed(the one Stamets specifies, 100 ft/min) with the area of your filter

100 ft/min x 2 ft2 = 200 ft3/min

So 200 ft3/min(= cfm = "cubic feet per minute") is the amount of air your blower must deliver at the sum of the STATIC PRESSURE of the HEPA filter + prefilter.

NOTE: 1 cfm= 1.7m3/h

So if you use the above filter with 1"(250Pa) static pressure and a furnace prefilter with a static pressure of 0.2"(50Pa) your blower must deliver 200 cfm(340m3/h) of air at a static pressure of 1.2"(300Pa).

Finding the correct blower
Every blower should have a data sheet with a characterisitc curve that shows the air output in dependance of the static pressure. Every blower has a data sheet (consult the manufacturer if this is not the case with your blower) where the correlation between the flow and the static pressure is represented by a graph or table.








is this correct with both 12 inch and 6 inch thick filters.
or is it that when the filter says for example 1000 cfm at .9" resistance you want a blower that can do 1000 cfm at 1.1" to make up for a .2 preffilter? Or is that too much i'm lost
another example this one http://www.ebay.com/itm/TRI-DIM-717112323102-24-X24-X6-99-97-HEPA-FILTER-/231135403657?pt=LH_DefaultDomain_0&hash=item35d0be5e89 is 600 cfm at 1" SP so would i then need a lesser of a blower than the first example (600 cfm at 1.2)? am i understanding this correctly?

Go with a little more than less on the blower & get a speed controller my dude.

You're making it much more difficult than it needs to be :thumbup:

i'm just trying to understand it. Is that eqaution (the quoted one) correct or outdated info? seems way off from the way i described it after. If someone could brake this down for me it would really help.

ok after i read this i think i understand it better


RogerRabbit said:
For that filter, select a blower which will deliver 250 cfm to 300 cfm @ .8" W.G. to 1" W.G.

The only reason I know that is I've calculated enough of them by now I remember the specs even without the data sheet.

You want 100 linear feet per minute of air leaving the front of the filter.

The filter is two square feet.

Therefore, you need 200 cubic feet of air being pushed through the filter.

To make up for losses due to friction, prefilter, inefficiencies in the blower, etc., shoot for a blower with 250 cfm to 300 cfm capability at 1" static pressure.  Once assembled, if the flow is too great, it's easy to stack up a couple of prefilters or block off part of the intake to get the correct flow.
RR




so i guess i need only 500-600 cfm at 1" or 400cfm at 1.2" ? for a 2'x2' filter and the FILTER's cfm rating doesn't matter????!!!!

go to page 3 of this link and read what RR says. they also discuss a blower that will work with this filter that has a very reasonable price from zorro

So Willy...how has the new hood been working for you? I'm curious about contam rates or any issues that may have crept up that were unforseen. This looks like a great hood!

in yuri's link RR talks about the blower not being big enough but I have to double check because the blower WW lists is 1 and a half HP. that is pretty damn strong! like I said I'm not an HVAC guy but that sure seems like it would get the job done. can't assume when you don't know though.




feel ya on that i had no clue what was up or down while building this. that is why i bugged folks til i got a answer. though to be honest the blower i got is a lot stronger and i was using the fan control and just dont use it now. so far so go. ill post back if i run into problems to let folks know. as ive been working with stuff all this month. WW blower might have been on point, but as stated "can't assume when you don't know though." that's why i asked for help. got mixed answers and went with RR advise.

BTW TB why not use the filter stated in the thread its dropped in price since ive bought one and it is 99.9995% on 0.1 to 0.2 micrometer particles

Hope WW is ok

Is that what those manufacturer tags said in the pictures the seller posted on them? I didn't recognize the format they were using.

Oh my woe my oh my this thread has gotten a few replies since I have been gone.  I am going to do my best to answer what I can and I hope it helps.  First things first though.  I am back.  I was dealing with life and I had some personal struggles on both financial and emotional levels.  Things are good now.  Life isn't perfect yet but it is getting there.  I have done a lot of stuff to take care of me. I want to thank each and every one of you who have shown care and concern for my wellbeing.  It really does mean a lot to me.  Much love to you all.:hug:and nowon to the replies to the replies...

time to see it put to use:thumbup:




    Part of the stuff going on with me had to do with housing.  I have a place to stay right now, but I do not have a place to grow.  I am exploring a few possibilities which might provide me a place/way to grow.  The hood is at my brother’s place waiting for a permanent home.  I did get a chance to do the lighter test and it was good.  I also turned the hood on and I did open an unused agar dish which I left sitting in front of the flow hood for about 20 minutes.  After that I put the lid on the dish.  I sealed the agar dish and set it aside to see what would grow.  I am happy to say that the agar dish did not contaminate.  So for the one thing I did get to use it for leans me to think that the flow hood and blower are doing what they are supposed to do.

Hi, thanks for sharing.
2 things:

No primary filter?

Can you please add some more pictures of the finished hood?

Regards




    Do you mean a prefilter?  I did use a prefilter I forget what exactly it was but I bought it at Sears.  It was a green plastic filter that I found in the area of the humidifier, air purifiers, and vacuum filters.  I cannot post pictures right now.  I would love to but the hood is in a garage in an entirely different county.  I am going up to my brothers for Easter so if I can I will take some pictures and post them.

gonna need a different blower just a heads up.




    I did quite a bit of research before I purchased the blower.  I used the information on the tag on the filter and talked extensively  with the company that made the filter.  I posted numerous threads asking for help.  After discussing my needs with AAF(think that was the company) I determined that the blower I purchased was a proper fit.  The thing with that filter is that it doesn't create a lot of resistance so a smaller blower works.

    I am doing well, but the place I am at has really dodgy internet connection.  I will post when I can as I can.  I might seem to go MIA again but it won’t be for nearly as long as I just was.  As soon as I can get into a situation that will allow me to grow I am going to put that filter to work.  Until then we won’t know for sure if the blower is going to work.  But I did open an agar dish in front of it and left it for 20 minutes and it didn't contam.  The hood also passed the lighter test.  I am confident that it will hold up. 

    Thanks to everyone again for showing an interest in what was happening with me.  Much love to you all.
