Our goal is to deliver first-class quality while providing a clean, healthy working environment for our employees. We were able to achieve this thanks to the air clean-ing systems from Zehnder. Our employees instantly noticed the difference. I can certainly recommend these units.

Walter Zwicklhuber, Owner and Managing Director


GEWA Blechtechnik GmbH is a leading contract manufacturer in the metal industry in Austria. The company produces a broad range of metal com-ponents that are laser-cut, stamped, edged and welded. The manual workshop and welding shop are full of oil vapours, dust and welding fumes, which can be detected in the form of metallic odours, a build-up of particles and visible mist. The managers at GEWA Blechtechnik wanted to change this situation. The goal was to implement measures designed to create a healthier working environment and significantly improve the general level of cleanliness and quality.


Thanks to solutions from Zehnder Clean Air Solutions, the particulate-matter load has been reduced by an average of 81% in the manual workshop and an average of 72 % in the welding shop. The metal-lic odour disappeared immediately after commissioning. What’s more, the units take care of air circulation, creating a pleasant indoor climate that is especially welcome on hot days. The amount of cleaning required has also been reduced substantially, as there is significantly less build-up of dust on the floor and on the machines.
