A 110v M-Class mini dust extractor is a compact, highly specialized industrial vacuum built specifically for building sites and workshops. The "M-Class" certification means it features advanced HEPA filtration legally required to safely extract medium-hazard dusts—such as those from hard woods, MDF, brick, and concrete—preventing harmful particulates from entering the air. The 110v power specification (often designated by a bright yellow casing or cabling) ensures it complies with strict construction site health and safety regulations when used with a portable transformer.
