AMSR Series Isolators have a unitized, adjustable open-spring isolator and a welded steel housing designed to resist seismic forces in all directions. Restraint surfaces which engage under seismic motion are cushioned with a resilient elastomer to protect equipment. The AMSR has a shipping block when installed internally to OEM equipment for protection during shipping.  AMSR Series Isolators with a shipping block are available in deflections up to 4 inches.

Features & Benefits

  • Rugged steel housing serves as blocking during equipment erection
  • Housing offers no difference in elevation between installed and operating height
  • Installation spacer ensures accurate installation height and adjustment
  • Top plate may be welded or bolted to equipment – allowing flexible design options
  • Housings are identical in height within each series
  • Easily accessible bolt holes permit simplified installation
  • Elastomeric acoustical cup eliminates high frequency vibrations
  • Color-coded springs permit ease of identification of load capacity
  • The shipping block and bolt allows the manufacturer to mount the unit fans on isolators, the isolators to be adjusted, and the complete assembly to be locked down for shipping
  • After equipment is installed, the installing contractor removes and discards the shim and bolt

Applications

  • HVAC equipment (internal isolation)
  • Air handling units
  • Fans
  • Pumps
  • Chillers
  • Condensing units
  • Engine gensets
