What is high-vacuum dust and fume extraction?

High-vacuum (hi-vac) extraction systems generate high levels of static pressure to pull dust, fumes, and other particulates through small-diameter hoses or tools. Unlike ambient air filtration or low-vacuum systems, hi-vac units are designed for source capture—removing contaminants as they are produced at the tool tip, weld seam or dust source. This method prevents airborne hazards from spreading throughout the facility.
