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" deflection spring elements. They provide excellent isolation of vibration over a wide frequency range.
Lateral Stability: The free-standing springs are laterally stable and designed to provide a 50% overload capacity.
Vertical Limit Stops: The adjustable vertical limit stops control the vertical and lateral movements of isolated equipment that are due to load changes and lateral seismic loads.
Ease of Installation: A built-in leveling bolt eliminates shimming in all applications and saves the cost of installation.
Effective Noise Reduction: The resilient washers interrupt structure-borne noise transmission paths. Noise amplifications caused by sounding board effects are thus eliminated.
