Matching fan for 2ft by 4ft HEPA filter
    #22214289 - 09/09/15 08:44 PM (8 years, 4 months ago)

I'm trying to build a laminar hood and the filter I ordered is 24in by 48in by 6in. So according to the calculation, I would need a fan performs 800-900 CFM @1"WC. Is it correct?

I was checking the hydroponic website for the inline fans. So should I choose 8" perform a little bit below 800CFM or 12" around 900 CFM? Please help!

i dunno bout inline blowers.

for squirrel cage top blower u want "dayton 1tdt2" fan model at minimum.

will blow 1040 cfm @ .8" SP.

150FPM should be a minimum IME, unless u have a nice lab, sealed, etc.

I am curious of the answers. Where did you buy the filter, better yet, how much?

Stop experimenting half way through your first grow. Grow it to maturity, watch it, learn from it. Do this a few times then experiment with different ideas and figure out what works best for you.

For a filter that size, you are going to need the highest volume dayton blower they make.

No, you want a blower, not just a fan.....

I found this blower seem matching my filter. Is this the right type of blower? I saw the data, it will reach 1600CFM@1"WC.

I'm in Canada, the filter I got is from air filteration.ca.

Not quite. I have a massive dayton blower i use to force air into the combustion train of my glass melting furnace. This thing would destroy a hepa filter
