Hello Tracy:

    I have a large hood over my casting machine and burnout oven with a
    powered roof mounted fan providing the suction. I purchased a Braun
    variable speed stove top vent, the kind installed in home kitchens. I
    installed it 18 inches over the top of my bench. I had the A/C
    contractor come in and install round pipe from the top of this vent
    and splice it into the exsisting pipe of my burnout oven vent going
    thru the roof. Turns out that I don't even have to turn my bench top
    vent on because the roof top fan pulls enough. I bought the variable
    speed stove top vent because I could turn it on at lower,Quieter
    speeds. I removed the 2 light bulb fixtures in the hood and installed
    a 24 inch florecent bulb fixture and that way I have the kind of
    light I want. I am about to install another of the same over a
    newley set up plating station. They cost about $130.00 plus, if
    mounting on the wall you'll use large shelve brackets and plus the
    cost of the vent piping. 

    I've been meaning to take a picture of my bench and post it. If you
    are paying to condition the air in your shop, you don't want too
    strong of a vent or you'll be wasting money.
