Seismic Rubber Mounts

Air Diffusion is at the forefront of designing innovative seismic restraint components which serve to limit the movement of equipment and to keep the equipment captive during a seismic event.

Seismic rubber mounts are designed to protect mechanical equipment from the extreme forces of a seismic event, whilst providing superior vibration isolation during normal use. 

These seismic mounts have been rigorously tested to AS60068.3.3 (see video below) and the patented method for adjustability allows the ultimate flexibility in height positioning and adjustment.  With multiple sizes and rubber hardness, there is an optimum solution for all types of mechanical installations.  When selected correctly, these seismic mounts are designed to suit the design requirements of AS 1170.4, NZS4219 and other international seismic standards.

Vibration isolated and resilient mountings

Components mounted on vibration isolators shall have a bumper or snubber in each orthogonal direction, and vertical restraints shall be provided, where required, to resist overturning.

Snubbers and their fixings shall be designed to resist the dynamic impact force imparted by the component on the snubber in an earthquake. Associated connections and piping shall have flexible connections to reduce the potential for damage.

Note:

  1. Ensure all vibration isolation mounts are approved for seismic use.
  2. The mount is rated appropriately to carry weight of the item and cater for the gradient of the ground
  3. When mounting plant on roofs ensure appropriate building structure is provided to mount item and seismic fixings.
  4. The mount must not under seismic action dislodge or come apart.
  5. All mounts must be fixed to appropriately rated building structure.
