AFS 152 Test System for manual scan testing of HEPA and ULPA filters according to ISO 29463-4 (EN 1822-4) and ISO 29463-5 (EN 1822-5) Main purpose of this air filter test system is determination of HEPA and ULPA air filter quality in terms of manufacturer production control. In its standard configuration the Manual Filter Scanner is adapted to an existing filter test bench. Aerosol generation is done by the Topas atomizer aerosol generator ATM 226 using standard DEHS test liquid. For upstream concentration measurement an optical particle counter is used in combination with cascaded self-adjusting dilution systems DIL 540. A scanning probe with a sophisticated x-y coordinating system is moved manually for downstream scanning of full filter area as well as filter frame. Same optical counter is used for downstream concentration measurement by using a sample switching unit SYS 520.
