ASI-E Type

Housed with Seismic Bushing
Acrefine ASI-E type Seismic Vibration Isolators are designed to restrain lateral and vertical equipment movement caused by external forces such as high winds or seismic events. The isolator housing is manufactured from high quality ductile casting. This design incorporates seismic steel bushing with elastic rubber, which improves the performance.
Equipment motion is limited to 6 mm (1/4″) which also ensures out-of-contact operation under normal conditions. The operational height of the isolator is fixed and any adjustment can be made via the adjustment nut located under the equipment bracket.
Vibration isolation is achieved by free- standing laterally-stable steel springs. All springs are assembled into elastomeric acoustical cups to eliminate internal noise. Springs are designed with 50% overload capacity and the lateral spring stiffness is greater than the vertical stiffness to assure seismic stability.
