    This is a TERRIBLE system ..  All this does is move stuff around and
    really stir up the bad stuff.. The really bad particulate  for your
    health are the  small ones that you can't even see. 

    Removing these is what HEPA (High efficiency particulate) filters
    are designed to remove. 

    I have posted stuff on hood design and  flow requirement a while
    back .. I lost  what I said  and the references included there  in a
    HD crash .. I will  have to put something together again  and get
    back with this. 

    Basically  you want  to remove the particles and fumes from your
    workplace not stir them  up.Ideally your work area  would be a
    laminar flow  zone  with all contaminates  removed  without  coming
    in contact with your lungs..
