>495 cfm .8" static pressure
>When i try to convert it on my calculator i'm keeping getting 14.02 M3 p/m
You calculated right actually.
It?s 14 m3/min
or 841 m3/h
.8" static pressure is around 200 Pa .

hmmmmm,
when you take a look here: http://www.mycotopia.net/teks/flowhood.html
they advice a 495 cfm blower to power a 12"x24" hepa filter figuring .8" static pressure.
maby cfm is cubic foot p/m instead of cubic feet p/m.
if it is cubic foot p/m its is 150 m3 p/m
I dont get it

1 cfm = 1 cubic foot per minute = 1.7 cubic meter per hour

>You will need at least a 495 cfm blower to power a 12"x24" hepa filter figuring .8" static pressure
The 495 cfm are at 0 Pa static pressure, free flow.
Once you place it behind the filter, the output at 200 Pa (= 0.8" ) is much less.

Well Anno,
They didnt had it on stock and i had to wait for 2 months.
And i hate waiting .
So this was the one i ordered,
and i'm only goin to use to inoculate petri's and jars.
no bags etc.
So i think this will be big enough.
Could you help me to decide wich blower sutes best?
Thanks,
Paddo

Well, they have radial fans:
3.1 RADIAL FANS Torin
700 m3 ( 90 watt) 91,00
You should ask for data sheet and look it up how much output this fan has at 125+50 or better yet 200Pa.
It should have 300 m3/h at 180-200 Pa if you want to use it.

wow... looking very trim there.
My gorilla just finished building his flowhood today and is very excited about it. I'll see if I can get him to post some pics of it soon.
It is using a large furnace fan with a 2X2 ft (609.6X609.6mm) HEPA and a dual layer electrostatic pre-filter (nothing fancy just a double layer of a special allergen furnace filter).
mmmmmm... gorilla like
