What Meidinger Ag does

Meidinger AG is a Swiss industrial fan manufacturer founded in 1900 in Basel, today headquartered and produced at a single ~3,000 sqm facility in Kaiseraugst, Aargau. The company designs and builds centrifugal (radial), axial, jet, and special/custom fans engineered for demanding technical applications where standard industrial fans are unsuitable, including explosive atmospheres (ATEX Category 1G, the highest Zone 0 classification), biogas handling, hygienic food/pharmaceutical environments, corrosive/toxic gases, dust-laden air, high-temperature exhaust, pressure-shock scenarios, and road/rail tunnel ventilation. Quality-critical manufacturing steps — impeller construction, welding of pressure-resistant vessels, static and dynamic balancing, and ISO 5801-compliant performance testing — are retained in-house, and the firm holds ISO 9001:2015, PED 2014/68/EU manufacturer and re-stamping approvals, INERIS Zone 0 certification, and EHEDG membership.

The business operates on a made-to-order model: every fan is adapted to specific customer performance requirements and quoted individually rather than sold from a price list. Revenue is generated from three streams — custom hardware sales, an aftermarket service bundle (commissioning, maintenance, revisions, repairs, exchange/rental devices) branded "Alles aus einer Hand," and original spare parts. Pricing is not publicly disclosed and contracts are typically multi-year in nature.

Go-to-market is sales-led and field-driven. Internal regional sales managers cover French- and German-speaking Switzerland, France/BeNeLux, Austria/Southern Germany, Northern Germany, English-speaking Eastern Europe, and tunnel projects, supplemented by external sales agencies (Thomas Eller in Northern Germany, Richard Theiss in Austria). Demand generation leans on direct relationships and memberships in industry associations including Fachverband Biogas, EHEDG, EUROVENT, and Swissmem. Since 1997 Meidinger AG has been a subsidiary of the German Witt Group, which provides international sister-company channels for tunnel fans and cross-border project reach; day-to-day leadership rests with Managing Directors Bruno Hüppi (Sales/Engineering) and Martin Pfammatter (Finances/Production), with Karsten Witt chairing the supervisory board.
