Sizing a Blower for Fume Collection
Sizing a Blower for Fume Collection
(OP)
I'm trying to size a blower for a fume (UF6 vapor) collection application. What I need is a reasonable assumption/guess for entrance velocity (CFM) for such an application. We don't anticipate much vapors. The application is to capture any vapor escape when making connections. Any ideas? Thanks in advance.

They have a range for contaminants released with almost no velocity into quiet air (Evaporation from tanks, degreasing etc. 50 - 100 fpm. Disturbing air currents, highly toxic fumes, heavy use and locations with a small hood would see the higher end of the range utilized.
If the contaminant is released at low velocity into still air the range for capture increases to 100-200 fpm.

it is just a 4-inch flex hose (there is no exhaust hood).
