ASI-T1 & ASI-T2 Types

Housed with Top Plate
Acrefine ASI-T1 and ASI-T2 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 welded steel. This design incorporates two restraining points that limit vertical and lateral movement of the equipment. The operational height of the isolator is fixed and any adjustment can be made via the adjustment nut located on top of the spring plate. Fixing holes are provided on the top plate for easy installation of equipment.
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.
