Walk-in and Low level fume hoods are meant as protective environments for the user, and are tested in accordance with EN 14175. Extraction of fumes, aerosols and dust from the internal workspace is performed to prevent dangerous amounts of pollutants from escaping into the lab, the formation of a high concentration of hazardous substances or potentially explosive atmospheres in the internal workspace. Walk-in and Low level fumehoods also protect from splashes of hazardous substances, from flying particles, bodies or parts escaping the internal workspace. They have the same features as standard Waldner fume hoods.
