If you have a window in front of your soldering station, a simple
soulution is to get a window fan. Place a plywood panel below it to
rase the fan unit to the desired height. then add another plywood
panel @ the top of the fan unit to allow attachment of a hood. The
hood can be made from sheet metal, perhaps 18 in across, with 6 in
sides, protruding about 30 in from the window. you can hang the hood
simply, from the upper plywood with hooks. Do your soldering benith
The fan would take the fumes confined by the hood and blow them
directly outside. If the fan blew in it would push the fumes into the
The hood should be about 24 in above the work space, made of sheet
metal for fire resistance. the top of the fan should be a few inches
below the hood to collect the rising fumes. an open window, even in
another room would replenish the air pushed out by the fan and
thereby help the venting work efficiently.
If your window is a double hung type, you will have to assemble the
above every time you work, if by chance it is a casement type window,
you can leave the fan in place and just open the window when needed.
This is my set up and it works just fine. You might want to leave
another window open to allow for make up air.
hope this helps,
