Another Flow hood build question..
    #25049900 - 03/08/18 04:28 PM (5 years, 11 months ago)

Hi all.

I know that this has been done a thousand times but i don't want to mess up and get the wrong thing when i build my first flow hood. I have been doing a fair bit of research on matching the blower and the HEPA filter and i think i have it right but just want to make sure before i pull the trigger.
I have read the Fungifun info on this topic and that was very helpful.
http://www.fungifun.org/English/Flowhood

So here it is:
I am looking at getting this HEPA filter.
http://www.newgenerationmushroomsupplies.com.au/index.php?route=product/product&path=110_123&product_id=140
it is 91.5cm x 61cm x 15 cm or 3ft x 2ft
= 6ft2

The blower i am looking at is a  Single Inlet Centrifugal Fans 200mm 240V with the following specs:


Voltage-220V

50Hz

Amps 1.8

Power input W 360

r/min 1300

M3/H 1365

static pressure 0

The link if you are interested.

My question is, is this blower and HEPA filter matched correctly?

Any guidance, help or suggestions will be greatly appreciated.
FYI i live in Australia so i can't get a professionally made laminar flow hood shipped here like i have seen other members of this forum get. ( for a reasonable price)If i am wrong, please send me the link :smile:

Thanks in advance

You need the chart that says what the blower pushes against more than Just 0 resistance

also the resistance of the filter would be helpful but you can just assume it's 1" w.g. which would be 2.54cm w.g.

so you need a blower that can push 600cfm (16.8 M3/min) at 1" w.g.(2.54cm w.g.)

Hi,
i have asked the supplier of the above mentioned fan for the chart but they have not gotten back to me, so I found this one...

https://www.ebay.com.au/p/250w-Centrifugal-Blower-Fan-Fireplaces-Pellet-Stove-900-M-H-Burners-Heating/918358641?iid=263511634438&_trkparms=aid%3D222007%26algo%3DSIM.MBE%26ao%3D2%26asc%3D20140106155344%26meid%3D92a8211eb8374fb2a192c5d4b24095fb%26pid%3D100005%26rk%3D3%26rkt%3D4%26sd%3D172842842830%26itm%3D263511634438&_trksid=p2047675.c100005.m1851

Max air flow is 1539m3/h or 900CFM





Am i correct in thinking that this is about half the blowing power i need for the above mentioned 6ft2 hepa filter and a prefilter with around 50Pa..?

If i am correct, would hooking two of these blowers up to my flow hood do the trick?

Thanks again and sorry for being a kook.

So i made the flow hood. Here are the pics of it.
Thanks again for your help Bodisatta.


The pre filter

Blower used is represented by the solid red line. I tried to get a different blower but they didn't have the one I was after so I went a bit bigger.
