Active isolation of large rotating machines that rotate at speeds exceeding 350 rpm and develop significant dynamic stresses (imbalance, short-circuit torque, such as compressors, fans, shredders, centrifuges, pumps, diesel engines, etc.)
Active isolation of presses, etc., with or without interposition of stabilizing mass.
Passive isolation of large civil engineering works, such as floating slabs, anechoic chambers, metrology rooms, laboratories, etc.
