Can you get a vent line to the outside? If so, the range-hood trick is the easiest and most likely least expensive method available. Keep in mind that most range hoods need only a 3" or 4" flexible plastic duct line which is extremely inexpensive. We've got a small wave-solder machine (12") that is vented to the outside with an 8 inch metal duct line. I've got the blower fans installed in a wooden box mounted to the inside surface of the outside wall - just before the vent louvers. The fans (2 of them) are 10" Rotron fans removed from old DEC PDP computer racks. The whole thing didn't cost more than a hundred bucks and a few hours of time. No solder fumes noticeable while the wave-solder is running. dwayne -- Dwayne Reid Trinity Electronics Systems Ltd Edmonton, AB, CANADA (780) 489-3199 voice (780) 487-6397 fax Celebrating 22 years of Engineering Innovation (1984 - 2006) .-. .-. .-. .-. .-. .-. .-. .-. .-. .- `-' `-' `-' `-' `-' `-' `-' `-' `-' Do NOT send unsolicited commercial email to this email address.
