Aeroff Oy is a story about persistency and motivation to improve working circumstances and conditions in metal machining. AerOff solution was invented in the applied research project originated by group of leading Finnish metal machining companies. The main target was to develop a solution for eliminating harmful aerosols from the output air which was widely identified problem in the metal machining industry. There were plenty of filters available in the market which can remove particles from oil mist, but they were incapable of removing or eliminating any harmful gaseous compounds. The project was established in 2015 together with Tampere University of Applied Sciences, VTT Technical Research Center (VTT.fi) and Finnish Institute of Occupational Health (TTL.fi). Both VTT and TTL are governmental regulatory institutions.
The problem was much more complex and difficult to solve than initially anticipated, but our inventor Pirkko Pihlajamaa was persistent and wanted to find a solution. Almost in the end of the project, Pirkko had one more idea that was tried – it worked and the AerOff solution was invented! The report from the research project can be found in Publications of Finnish Institute of Occupational Health 2016.
The commercial preparations for the AerOff solution started in a second research project by Tampere University of Applied Sciences and Finnish Institute of Occupational Health, funded by Business Finland in 2016. In this extensive project altogether three prototypes were built and installed to a real factory environment and their purifying results were proven with accredited measurements. Each prototype was developed further and thus representing a more advanced generation of the AerOff Solution. Hanna Pihlajarinne, Jussi-Pekka Juvela and Lasse Hillman joined in the project with Pirkko. After this project was finished 2019, also Timo Nykänen joined the team and Aeroff Oy was established.
