Innovation story

When changing the oil in his Volvo 244, Veikko Valli wondered why dust seems to accumulate on certain parts of the radiator’s surface.

He had a long career in developing solutions for the steel industry and remembered the phenomenon while looking for a solution to the dust problem of an industrial customer.

Dust accumulation follows the laws of flow dynamics.

This scientific finding is the foundation of Filtrabit technology and business.


  • Established in 2011 to develop and commercialize an innovative dust separation system.
  • Developed dust separation through flow modelling together with the University of Oulu. Professor Pekka Mäntylä, who participated in the study, became a shareholder in the company.
  • Manufactured the first flow dynamics prototypes in the early 2010s.
  • In 2017, the EU’s Horizon 2020 research framework programme awarded Filtra Group Oy a grant of EUR 1.6 million with the highest evaluation score in the history of the programme.

Capital efficient solution

Filtrabit can offer dust separation as a turnkey solution. It includes the operating lease of the flow-dynamic filter, as well as complete designs for the ducting, hooding and dust handling systems.
