AFS 152 – Manual HEPA/ULPA Filter Scanning Test System

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 application of a sample switching unit SYS 520.

  • Test protocol fully compliant to EN 1822-4 and EN 1822-5
  • Cost effective testing by manual x-y scanning operation
  • Fully automated aerosol generation, upstream/downstream particle counting and test data acquisition
  • State of the art aerosol instrumentation
  • Quality control and assurance in HEPA and ULPA filter production
  • EN 1822-3: MPPS determination of filter media (using optional AFS 153)
  • EN 1822-4: determination of local filter efficiency, leak detection
  • EN 1822-5: determination of integral filter efficiency
