Abstract
Embodiments of the inventive technology include a centrifugal fan having a damper repositionable between a closed position and a fully seated open position, and a magnetic coupler that serves to fully seat that damper it its open configuration, so as to prevent undesired effects such as slippage and/or rocking of that damper relative to rotatable componentry against which it is pressed, during operation of the fan. The coupler may be configured so that the damper may decouple from rotatable componentry, e.g., upon a certain reverse pressure differential, and translate to a closed position.
