The aperitif in the foyer of the KKL, accompanied by a product exhibition, was followed by dinner in the festively decorated Lucerne Hall. At the centre of the celebrations was the historical review presented by the owners Tobias and Christoph Meyer.

In the 50 years, both the first and the second generation of the Meyer family have shown that they have the intuition and the vision for the needs of the market. With factory expansions in several stages, the company adapted to the increasing demand again and again. The Meyer brothers demonstrated farsightedness during the economic crisis in the 1990s. Contrary to the market trend, the level of automation was increased with the investment of a sheet metal processing centre and a fully automatic powder coating plant. Thus Seven-Air was ready for the following upswing.

Looking back, Tobias Meyer proudly mentioned winning the Prix SVC in 2018 and being a finalist in the "Entrepreneur of the Year" competition. The impressive film passages on the Roche buildings 1 and 2 as well as the pRED (building 4 to 7), for which Seven-Air was allowed to supply all ventilation units, led back to the present. Due to the still unique product quality and the market successes launched in recent years, the traffic light for Seven-Air remains green.
