The Vibro-Acoustics Seismic Free Spring (SFS) series provide vibration isolation for mechanical systems and equipment. The SFS isolator has a seismic restraint housing for greater lateral and vertical support. Springs are engineered to provide an additional 50% overload capacity.

All other hardware is zinc plated, including the adjustment nuts used secure the isolated equipment. Housings are powder-coated to fit its environment. The SFS isolator also comes with an all-directional elastomeric snubber to prevent metal-to-metal contact between item components.
