AFR
Measuring the Airflow Resistance of Porous Materials

The AFR (Airflow Resistance Measurement) system was designed to measure the airflow resistance of porous materials in an easy way without compromising in terms of measurement quality. The measurement results of the AFR system comply with ISO standard 9053:1991.

The AFR system offers:

  • An extremely robust, stable, durable and high-quality construction
  • Easy and intuitive operation also for non-experts
  • Measurement of thin materials (fabrics or non-wovens) thanks to a special sample holder
  • Rapid and easy fixation of measurement samples
  • Easy transportation

Technical specifications:
