Regulating damper with opposed and aerodynamic vanes, manufactured in aluminium, KOOLAIR, model AOBD-102-E. The body of the damper has built-in air tight gaskets all around its inner perimeter to ensure a tight seal. The movement of the vanes is ensured by means of gears, achieving a proper friction, with manual or motordriven operation.
Vanes are available with 75 and 100 mm vane axis distances, to complete the entire range of standard duct dimensions. Finishes in natural aluminium.
