Demsan Electricity and Ventilation, which started its activities in the sector with the production of the electric motor used in solid fuel boilers, was established in Istanbul by the late Bayram Demirci in 1992. The company, which started to produce axial fan motors only 5 years after its establishment, moved to its current location in 2002. As a result of the development and investments in the production processes, it has started to produce mass production since 2005 and started the production of boiler fans from this date. Demsan Elektrik ve Havalandirma started the production of duct fans in 2008 with its continuous development and growth approach. Following the processes that followed this development, in 2015, it started to produce products for the ventilation sector.
