Services - Particle Filter Testing

We perform tests on filters and filter media even down to granulated active carbon or carbon beds, according to ISO 16890, EN 779, EN 1822, ASHRAE 52.2 or ISO 11155 / DIN 71460 amongst others. Our test reports ensure a maximum of reliability and meet the highest demands. From global players to regional suppliers, many companies trust in our experience and know how.
Particle Filtration Testing
  • Pressure drop tests
  • Fractional collection efficiency using a wide variety of aerosols and dusts
