Wolfgang Hassa
Who would have thought that studying aircraft construction at FH Aachen would someday lead to a patent in the cleanroom industry? Wolfgang Hassa certainly didn't, when in 1990, after completing his studies, he spent several years as a professional hot air balloon pilot flying across Germany.
After his adventurous years, he worked for 10 years at GEFA-FLUG mbH in Aachen as Production Manager in the balloon and airship construction division. From this time, he gained extensive knowledge about fabrics, fabric stresses in large volumes, and various textile processing techniques. The necessary handling of standards and documentation in aviation also made up a large part of his work.
After completing a postgraduate degree as an industrial engineer, he gained experience as a management consultant in factory planning and then returned to GEFA Flug first as a authorized signatory and later as managing director.
In 2015, he became self-employed with his company Airworxx, which specialized in inflatable textile 3D bodies for events, art, and trade fair construction. Through Airworxx, the first innovative cleanroom made of fabric was built in 2016 – the sphairlab.
In 2018, together with Cleansman Jens Hutzenlaub, the sphairlab GmbH was founded, including the development of the patent on the construction principle of the sphairlab.
In 2021, he independently founded Reinraum-Mieten, a company specializing in the rental of fabric cleanrooms in a modular system.
