TVE 3000 Filter Media Tester

With the aid of the TVE 3000, vacuum cleaner tests can be carried out more cost-effectively than in accordance with the standard EN 60312. In addition, it is 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 within the salt generator AGK 2000. The dust disperser RBG 1000 that is used operates much more uniformly than is required in the standard and therefore delivers an optimized dust application, which is a prerequisite for exact measurements of separation efficiency with a particle measurement device.
With the particle measurement system Promo® 2000 with the aid of the welas® 2300 aerosol sensor in the clean gas, the emissions of a vacuum cleaner can be measured in accordance with the standard. As a result, not only is it possible to accurately compare vacuum cleaners, but the individual filter stages can also be reliably assessed.
With the particle measurement system Promo® 3000, users have access to a high-resolution aerosol spectrometer for virtually simultaneous determination of the particle size distribution and the particle concentration in the raw gas and in the clean gas.
The welas® 2070 aerosol sensor accurately determines the measurement in the raw gas, while the welas® aerosol sensor 2300 performs the measurement in the clean gas, allowing the fraction separation efficiency of vacuum cleaner bags and HEPA end filters to be performed.
