In 1987 the company was founded as single-member company by Ing. Heinz Aigner. Business has been running so well, that Aigner GmbH emerged from that in 1998. In 2007 Aigner Holding GmbH was founded, which today implies three successful subsidiaries:
Aigner Tunnel Technology GmbH In 1990 Aigner already started with the development and the production of electrostatic filters for exhaust gas removal in road tunnels.
