Faudi Aviation

What Faudi Aviation does

Faudi Aviation GmbH, operating under the holding brand "sefiso," is a German family-owned industrial manufacturer headquartered in Stadtallendorf. Founded in 1938 and currently employing 101-250 people, the company designs and produces filtration vessels, filter elements, and fuel condition sensors for civil and military aviation, alongside industrial diesel, process, air and gas, and general fluid filtration solutions. Its product portfolio spans four business units: Aviation, Industrial, Training (SAFE Academy), and Digital (CONNECT platform). The company maintains wholly-owned subsidiaries in Germany, the United States (Newark), the United Kingdom (Milton Keynes), Ireland (Dublin) and Brazil, complemented by a global network of trading partners and distributors. Sub-brands include Avifil, FAA-Filters, FAA-DO Brazil, FAUDI-Americas, FAUDI Diesel and FAUDI Aviation itself.

Revenue is generated through one-time hardware sales of filter elements, vessels and sensor/monitoring systems, complemented by a subscription/recurring layer via the CONNECT digital business platform and professional-services revenue from the SAFE Academy. Pricing is quote-based and not publicly disclosed, consistent with B2B enterprise sales to aviation operators, fuel handlers, defense customers and industrial buyers. Go-to-market combines direct enterprise sales through subsidiaries and the CONNECT platform with e-commerce via a dedicated webshop and channel sales through a global distributor network. The legal entity is FAUDI Aviation GmbH (Germany), and the firm is led by Managing Directors Marcus Wildschütz (President), Mathias Aden and Jürgen Buss, with no recorded external investment or private equity involvement.

The company is managed as a long-tenured Mittelstand operation with multi-decade domain expertise in aviation fuel filtration, single-digit product adjacencies (industrial filtration, training, digital services), and a multi-regional operating footprint. Day-to-day technology integrations are limited to commodity tools (JitBit for support, Google Analytics and Google Maps on the public site), with no disclosed AI, no public patents and no public awards or certifications beyond the regulatory positioning implied by the FAA-Filters sub-brand.
