OT; Central Heat and Air

[imsqueak]

I closed in my garage to make an office. Seems splitting my LR tube isn't giving me enough flow to cool the room. I've invented a fan in my mind but don't know if one exists - I invent many things in my mind that should be on the market but aren't.

Is there a fan thing that I can put in my air discharge that will multiply the output?

It's called an "Inline Inductor Duct Fan Booster". Do a Ebay search, they run around $25.

It will work, but not very good. They aren't rated at a very high CFM, and if you duct work is sized right, you will be robbing air from another register. I think that the C.C. Dickson in Knoxville sells them (we do here in Bristol).
