Richard, I had used FUMEX filtration systems previously to remove solder fumes from various solder processes. While I have not used them on wave soldering, they do capture any exhaust from a process rather well. They come equipped with a charcoal filtration system. Their website is: http://www.fumexinc.com/ I suggest that you might have to retrofit the exhaust to your wave soldering system. The exhaust fans on the wave soldering systems I've worked on, when down for maintenance, were able to supply enough exhaust to remove any fumes from the unit. I estimate that the exhaust systems I worked on was rated between 100 - 500 CFM. This includes emptying the solder pot. The location of the wave solder is important as well. If the area is not well ventillated, you may have more problems with exhaust fumes. Hope this works. If there are any questions, please call me directly.

When the 'top' of the wave machine is opened for maintenance the exhaust system does not work and the fumes fill the room. I was wondering if anyone else either does have a unit or is considering a unit for this. I am interested in experience and opinions. Feel free to reply directly to me off line if you like. And, Thanks in advance!
