Acrefine ASI-T1 and T2 ASI-type seismic vibration isolators are designed to prevent the lateral and vertical equipment movement caused by external forces such as winds aloft or seismic events. And the insulator body is made of high-quality welded steel which has restraining points to limit the movement of equipment vertically and horizontally.

The operational height of the isolator is fixed and height adjustment can be made with the help of adjuster nut which is located on the top plate. The fixing holes are located on top of the plate, enabling easy installation of the equipment.

Vibration isolation is provided by steel springs that has legs. All of the springs are mounted in elastomeric acoustic containers to eliminate internal noise. The springs are designed to carry out fifty percent overload capacity. The lateral spring stiffness is greater than the vertical stiffness in order to ensure seismic stability.
