Farrat’s range of heavy duty structural coil spring isolation systems provides low frequency vibration isolation for large structures and industrial equipment. They have been used worldwide for a wide range of applications.

FSL Coil Spring Isolation systems are used to provide both active and passive vibration isolation with natural frequencies down to 3Hz to isolate disturbing frequencies down to 6Hz. Where a system is likely to pass through or near resonance and excessive movement is a concern it is recommended that FV Viscous Dampers are used in conjunction with the FSL springs. This combination of FSL Coil Spring Isolators and FV Viscous Dampers also provides excellent shock absorption.

FSLV Coil Spring and Viscous Damper Isolators combine an FV viscous damper into a modified FSL Coil Spring Isolator to provide a compact integrated unit.

Load range from 3kg up to 3,818kg per mount.
