Help picking a blower for a flowhood
    #27301461 - 05/09/21 10:32 AM (3 years, 10 days ago)

I just ordered this HEPA filter and I have 60-90 days to wait until it ships so I have quite awhile to find a good blower for it.

The manufacturer lists the filters w.g. at .79.  And I'll probably put a cheap furnace pre-filter on it too.  I read these run about .2 SP.

So, my understanding from this link is I need a fan that hits 200cfm at 250pa.

But I've also read I should add 10% to that number?  But also not go over 20%?  lol

Can anyone clear this up or give some suggestions on good places to get a fan on the cheap?

This is my first flowhood build and I want something semi-portable.  Any advice would be appreciated.
