Short description
The guideline VDI 4709 provides information for building owners, planners, operators, building users and installation companies about the planning, calculation and execution of central vacuum cleaning systems and proposes minimum requirements for suction power and noise emissions. The popularity of central vacuum cleaning systems is on the increase in Germany, because their advantages are obvious: they do not contaminate the indoor air with fine dust, like conventional vacuum cleaners do. In central systems, the dust is evacuated by a central appliance and directly released into the outdoors. In the individual rooms, all that is necessary is a hose with a nozzle, which is connected to an inlet valve. This hygienic way of vacuuming is the key advantage over mobile vacuum cleaners. The operating noise of the appliance is also less audible if the central appliance is installed in a remote or well-isolated room. Central vacuum cleaning systems used in residential buildings, business and administration buildings, banks, hotels etc. can protect people's health by reducing or avoiding fine-dust contamination, which is of benefit especially to allergic persons.
