Seismic Zone 2 Capability: The housings and anchor bolts are optimally designed for seismic zone 2
applications.
Superior Isolation Efficiency: Series "820" spring isolators consist of welded housings and 1 inch
deflection spring elements to provide excellent isolation of vibration over a wide frequency range.
Lateral Stability: Free-standing springs are laterally stable and designed to provide 50% overload capacity.
Vertical Limit Stops: Adjustable vertical limit stops control vertical and lateral movement of isolated
equipment due to load change, and lateral seismic load.
Easy To Install: Built-in leveling bolt eliminates shimming in all applications, and save installation costs.
Effective Noise Reduction: The resilient washers under the springs effectively interrupt structure-borne
noise transmission paths to prevent noise amplifications caused by sounding-board effect. The resilient
washers replace the neoprene base pad to allow solid connections of anchor bolts and base plate.
