Acrefine Seismic Spring Isolator

Restrained Spring Isolator with Steel Housing

Acrefine ASI-V 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 fabricated from high quality steel. 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.
