Similar to the standard STACIS Quiet Island, this Compact version provides excellent sub-Hertz active floor vibration cancellation for large instruments that typically weigh over 1134 kg (2,500 lbs.).
Whereas the standard Quiet Island requires a raised floor or pit with a depth of at least 380 mm (15 in.), Compact Quiet Island utilizes STACIS IIIc low-profile isolators and custom pocketed platforms to match raised floor heights as low as 200 mm (7.86 in.).
The images below illustrate the height comparison between the standard and Compact Quiet Island heights.
