Big Server Fan Becomes Fume Extractor
Anthony Kouttron wanted a fume extractor for his electronics lab but was unimpressed with the commercial options, so he decided to build one himself. His design centers around a powerful 110-watt centrifugal fan, originally from an IBM server, which is capable of moving about 500 cubic feet of air per minute (CFM). Given that this fan is a high-performance, expensive component—retailing for over $200—Anthony paired it with off-the-shelf HEPA and activated carbon filters to ensure it effectively captured harmful particles and fumes. He opted not to DIY the filtration system since the filters are critical to the safety and performance of the fume extractor.
To make the unit more versatile, Anthony built a custom power supply for the 12-volt fan, allowing it to run on standard drill batteries. This practical choice makes the extractor portable, adding to its usefulness for various situations. While such a high-powered fume extractor might be overkill for the average hobbyist, it provides an option for those concerned about the hazards of soldering or 3D printing fumes. For anyone interested in a serious DIY fume extractor, Anthony’s project serves as a solid starting point.
