It could be 1600cfm but without more specs don't buy it.

It may drop to 50cfm @ 1sp

Filters have resistance. Some fans have more ummpphh than others.

If your fan doesn't have enough muscle it won't be able to provide laminar flow when paired with your filter.

if you don't know about how to build a flow hood why are you building a flow hood. you don't need one until you understand one.

you need to get the graph of the blower against static pressure

you could have two 1200CFM blowers and if you put a 1SP HEPA filter up to both of them. one of them may end up pushing 200CFM and the other 50CFM.

amps volts ohms but with air.

It's like Ohms law but with air flow.  AmpxResistance=Volts or some shit.

  The point is that you static pressure is the amount of air build up in the space between the output of the blower and the resistance of the filter. If you Hepafilter is rated it will have a graph showing how much volume vs the pressure of 1sp to produce even laminar air flow over the surface of the filter. I think I typed that correctly. Im not the smartest guy In the thread, I just have the experience of purchasing two blowers because I did the math wrong the first time. Don't be me, do the math!

U can use that fan but will probably need atleast 2'x2' of filter to be able to swing it.

It's very easy to choke a fan or add a cheap speed controller to regulate it down.

I have a flowhood thread somewhere where I show how to do this if you want to see it :thumbup:
