S900BA – NCA Series Volume Control Damper cooling fan DimensionsThe NCA 9000 series of volume control dampers was designed to handle light and medium velocity applications better than all other control dampers in its class. Utilising the HVC standard out of airstream linkage, all gears are protected from dust and dirt by being positioned within the channel outer frame, making S900 dampers less susceptible to requiring frequent maintenance than rival units where the linkage is within the airstream.
