Dust Environment Test Blower
I have a 50"x18"x15" (7.8 ft^3) box that I am trying to create a dust environment for testing purposes. The idea is to have sawdust circulating in the box getting everywhere. I was thinking that a couple squirrel cage blower on opposite ends would get the job done. However, I don't know what CFM rating I would need in order to create this environment and I am also looking to be able to vary the speed.
