Scanning of 3d filter dimensions by means of collaborative robotics

From the current state of the art HEPA and ULPA filters are classified by its integral and local filtration efficiency. Local efficiency measurement and leak detection requires a filter scan. For two-dimensional filters this is typically realised by a traversing system. So far it has not been possible to determine local efficiency of three-dimensional filters such as HEPA cartridges with a two-dimensional scanning. Therefore, there is a special section at ISO 29463-4 accepting integral testing for filters that cannot be scanned.

With the integration of latest collaborative robotics technologies to our new AFS 151 Automated HEPA/ULPA Filterscan Test System our engineers made it possible to scan three-dimensional filter geometries. This gives a big chance to filter producers increasing their product quality from improved local efficiency determination.

With the AFS 151, we are the test experts of HEPA filters and combine modern robotics with proven Topas aerosol technology and test system quality. Live demonstration for curious minds: Meet us at FILTECH 2024 in Cologne and find out for yourself.
