4V-SH ANTI-SEISMIC MOUNT
The 4V-SH Anti-Seismic Mount is a heavy-duty spring mount from AMC Mecanocaucho that provides low-frequency vibration isolation combined with seismic restraint. It is designed for mechanical equipment such as pumps, fans, and HVAC plant installed in buildings where both vibration control and seismic protection are required.

- Spring variants: Blue (268 kg), White (380 kg), Black (492 kg), Beige (692 kg), Red (892 kg), Grey (1,340 kg), Green (1,784 kg), Brown (2,800 kg)
- Levelling system: Incorporated
- Secondary isolation: Sylomer pad under mount base for mid to high frequency attenuation
- Operating temperature: -30 to 70 degrees Celsius; short-term higher temperatures possible
Applications
Suitable for isolating rotating and reciprocating machinery in commercial and industrial buildings where seismic loading must also be considered. Typical installations include air handling units, chillers, compressors, and pump sets mounted on structural slabs or roof plantrooms.
Frequently asked questions
What does the Sylomer pad under the base do?
The Sylomer pad works in series with the steel spring to attenuate mid to high frequency vibration that the spring alone would transmit. The spring handles low-frequency isolation, and the Sylomer pad addresses the higher frequency residual.
How do I select the correct spring colour?
Spring colour indicates load rating. Each colour corresponds to a maximum supported load ranging from 268 kg (blue) up to 2,800 kg (brown). Select the variant whose load rating matches the supported equipment weight per mount.
What is the operating temperature range?
The mount is rated for continuous use from -30 to 70 degrees Celsius, with short-term exposure to higher temperatures permissible.
