Any equipment either rotor or stator will have its own CS (critical speed) or natural frequency which when excited results in structureborne vibration and airborne noise in the building. By designing the rotor we can minimize or ensure the equipment operates below or higher to its critical speed. But that is an ideal situation. A quick solution for currently operating equipment is to avoid such noise/vibration issues with a product called ‘pad isolators’.

Anutone’s Noizkon division has extensive expertise and experience in designing and manufacturing innovative products to control noise/vibration in technical collaboration with Kinetics USA, and pad isolators is one of them, distinct from neoprene or spring isolators. Pad isolators are precompressed, moulded glassfibre-based cubes that can be incorporated into innovative floor isolation systems.
