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
