FHS Spring Isolator

Kinetics Model FHS Seismic Spring Isolator

*Click here to see sizes stocked in our warehouse!*

Kinetics Model FHS Seismic Control Spring Isolators are recommended for noise and vibration isolation for mechanical equipment located near critically quiet areas when there is a possibility that the equipment to be isolated will be subjected to the external forces associated with an earthquake.
Model FHS isolators are used to reduce the transmission of noise and vibration into supporting structures from supported mechanical equipment. Motion during an earthquake which would otherwise displace life support and emergency equipment is limited, and the equipment remains in position. Anchorage of Model FHS isolators should be designed by a professional engineer and isolators selected based on calculated anticipated forces.
  • All-directional restraint with vertical limit stops
  • Field-interchangeable spring coils
  • Galvanized housing and polyester powder coated coils
  • Constant free height & operating height
  • Equipment motion limited to 0.2" (5 mm) in all directions, at the isolator
  • California Pre-Approval Number R-0433


Model FHS Seismic Control Spring Isolators meet specifications for Kinetics Model FDS isolators and include a steel housing assembly to limit both lateral and vertical movement of the supported equipment during an earthquake without degrading the vibration isolation of the spring during normal equipment operating conditions.
Standard FHS isolators incorporate a steel housing which encloses a neoprene snubber. Depending on the load and seismic code, an optional steel load spreader plate may be applied to distribute the load among concrete anchors. A neoprene pad fitted in series with the spring is provided. Equipment attachment is by way of a bolt screwed downward through the equipment foot.
Removal of the isolator for servicing can be easily accomplished as the isolator is not fitted with a protruding stud. In conformance with all current building code standards, the restraining system is designed to withstand a minimum 1.0 g acceleration force. Equipment motion is limited to approximately 0.2" (5 mm) in any direction, at the isolator.
