With the aid of the model group TVE 3000, vacuum cleaners are tested more reliably and more cost-effectively than as per the definitions in the standard EN 60312.
With the TVE 3000, it is also possible to distinguish the separation behavior of vacuum cleaners with bags and vacuum cleaners with bags and HEPA end filters reliably with with dust or as an option with salts – e.g. NaCl or KCl. The raw gas and clean gas measurements are performed virtually simultaneously.
This makes it possible not only to accurately compare vacuum cleaners, but also to accurately assess the individual filter stages.
