ABP 115 – Air Intake Filter Test System

The Engine Filter Test Rig ABP 115 performs tests according to guideline ISO 5011 (test of inlet air cleaning filters for internal combustion engines). Results are:

  • Differential pressure related to air flow rate:
    • Differential pressure of the filter
    • Restriction (relative pressure against ambient)
  • Dust loading capacity (related to differential pressure increase, e.g. 20 hPa)
  • Gravimetric efficiency


  • Powerful two-stage generation of the volume flow
  • Precise flow rate measurement with adjustment for every application (ISO 5011)
  • Regulated dust dosing
  • High grade of automation, mostly automated test runs with complete operator guiding, data handling and protocols
  • Tests of engine intake filters according to standard ISO 5011
  • Tests according to customer-specific standards
