Need help venting fumes out a window

[muibubbles]

I hope this is the right section....

I need help venting fumes out of my window. And although it is not for a garage I though you guys will have the answer....

I am screen printing in my basement and when i cure the ink on the shirts the heat/shirt/ink is giving off some fumes... it gets a little smokey/cloudy in the basement after a few hours so I'd like to vent it out of the window.

I dont know what the window style is called but it is hinged on the bottom and pulls in... I'm not sure if i can remove the actual window, but if I can, I dont mind doing so to make the exhaust system...

I figure id make some sort of hood over my flash dryer (heater) and have ducting run out the window with a blower/fan to **** the air... Has anyone done this? how much cfm do i need? its and open room thats about 14'x12'...any help would be great, Thanks!

How about mounting a regular kitchen vent over the window opening and set it up to blow out the window. Just be sure you get one that doesn't just recirculate the air back into the room. Most of them today are that kind. With a little thought, you might even be able to set it up so that you can open and close the window. The exhaust air needs to blow through the window opening, but there doesn't necessarily have to be a duct through the window opening.
Another approach would be to get a good size muffin fan (or several small ones) and mount them to a piece of plywood that fits the window opening. Open window, stick the board in the opening, plug in fan board. When work is done, take the board out and close the window.

That sounds like a "transom" window, where the top tilts into the room?
The easiest way to fit it with an exhaust hose may be to make a lightweight box of tin or thin plywood, with a 4" hose fitting in it, and "hang" the box over the open window, so that it basically covers the opening and fits up against the wall around the window.

Then use a small in-line exhaust fan to go between your vent hood and the window box.

Or, just replace the glass with a sheet of exterior plywood or plastic with a vent hole in it for your hose.

How big is the area that's emitting fumes?

If it's small enough, you could use something like this:

I have one of these on my hobby bench, and it works well.

How much CFM a hood needs depends on lots of things. You would have to design the hood first, then figure out the correct airflow for it. You need to figure out capture velocities and whatnot.

You need to be careful not to exhaust the space too much without a supply of make up air as well.
