Laboratory suction units are dust and debris extraction systems connected to grinding, trimming, and polishing workstations, drawing airborne particulates generated during acrylic, metal, and ceramic processing away from the technician's breathing zone. Effective suction is a core occupational health measure in dental laboratories, reducing exposure to fine dust from model trimming, lathe polishing, and framework adjustment. Suction units are typically integrated into or positioned alongside lathes, trimmers, and sandblasters, making them essential infrastructure for maintaining air quality and regulatory compliance in any laboratory workspace.
