Airleben

What Airleben does

Airleben GmbH is a privately held German manufacturer and specialist distributor of ventilation duct systems, organized as the airleben Gruppe with its headquarters in Leipzig and a nationwide footprint of seven production and logistics sites across Germany (including Leipzig, Hammelburg, and Gotha). Founded in 1999 (originally as Gothaer LBG GmbH, rebranded in the 2010s), the company has operated for over 25 years and serves exclusively professional trade customers (SHK-Handwerk) in residential, commercial, industrial, and public-building applications.

The company's core offering spans rectangular and round air ducts (in galvanized steel, aluminum, stainless steel V2A/V4A, black steel, and thermoplastics), sound damping systems (cassette, panel, pipe, telephone, and compact silencers), protection and regulation components (louvers, weather and bird grilles, flexible connectors), and roof components (hoods, deflectors, penetrations, nozzles). Products comply with DIN EN 1505, 1506, 1507, 12237, and 16798-3 standards and achieve air tightness classes B, C, and D. Proprietary items include the Superdichtecke (SDE) flange sealing corner and the airSILENCER online dimensioning tool. In 2024, the group added AxiomPlastics GmbH (formerly its Kunststoff Kompetenz-Center) and rolled out a new ERP system.

Revenue is generated through a multi-channel model combining technical-consulting direct sales, the airleben24.de self-service online shop, and project logistics with delivery to warehouse or construction site. Adjacent services include technical consulting, project logistics, the airAcademy seminar program (covering VDI 6022, fire dampers, air tightness, plastic welding, refrigeration certification), mobile air-tightness testing per DIN EN 16798-3, and resale of complementary products from brand partners such as TROX, Helios, Schako, Nicotra Gebhardt, ruck, 2VV, Ergovent, AIRFLOW, and geba. The company is not venture- or PE-backed, operates only within Germany, and does not disclose revenue.
