In Germany, specific limit values apply to air velocity at industrial workplaces, resulting from an interplay of occupational health and safety regulations, technical rules, and European standards. The most relevant frameworks are DIN EN ISO 7730, the DGUV regulations, and the Technical Rules for Workplaces (ASR A3.6). What matters is not only the pure air velocity, but also the air temperature and the degree of turbulence at each individual workplace. The following sections answer the most important questions about standard-compliant ventilation in industrial operations.<\/p>\n

What specific limit values apply to air velocity at industrial workplaces?<\/h2>\n

For industrial workplaces in Germany, the general guideline is a maximum air velocity of 0.2 m\/s for sedentary activities and up to 0.35 m\/s for physically active work. At elevated room temperatures, higher values are permissible, provided the air movement is perceived as comfortable. The exact limit values depend on the type of activity, the room temperature, and the degree of turbulence.<\/p>\n

ASR A3.6 “Ventilation” specifies these requirements for workplaces. It distinguishes between natural and mechanical ventilation and stipulates that draughts must be avoided as a source of discomfort. For typical industrial activities involving moderate physical exertion and a room temperature of 20 to 24 \u00b0C, the recommended range is between 0.15 and 0.25 m\/s. At temperatures above 26 \u00b0C, higher air velocities of up to approximately 0.5 m\/s may be acceptable, provided employees agree and this contributes to cooling.<\/p>\n

Which standards and regulations are authoritative in Germany?<\/h2>\n

In Germany, three sets of regulations are primarily authoritative for air velocity at industrial workplaces: DIN EN ISO 7730 (thermal comfort in indoor environments), ASR A3.6 (ventilation in workplaces), and DIN EN 16798 (energy performance of buildings and ventilation requirements). These are supplemented by the DGUV regulations and the Workplace Ordinance (ArbSt\u00e4ttV).<\/p>\n
