BVN, whose sign reads "Havalandırma Sistemleri & Elektrik Motorları", shows an axial fan, a plate-mounted fan and roof fans on red plinths. In the foreground, a unit with a transparent lid marked "Counterflow Heat Exchanger", "Supply Air" and "Return Air" reveals its interior, while a white plinth by the amster.pl and Nortada area holds roof and duct fans.
