The AMC-MECANOCAUCHO® ST+Sylomer® range has been developed for demanding building acoustics and stationary machinery applications where exceptional structure-borne noise isolation is required.
By combining a steel spring with a Sylomer® element, these acoustic hangers provide outstanding vibration isolation across a wide frequency range while maintaining excellent long-term stability. Depending on the model, natural frequencies as low as 3–4 Hz can be achieved, making them ideal for low-speed equipment operating between 600 and 1,000 rpm.
Typical applications include HVAC ducts, suspended mechanical services, piping systems, ceilings and other installations requiring high-performance vibration isolation.
The design of these acoustic hangers is composed of:
1. Metal parts that are mechanically failsafe.
2. A rubber moulded part equipped with an end stroke buffer if ever the acoustic hanger is overloaded.
3. A prime degree steel coil spring to provide low natural frequency to the acoustic hanger.
4. A Sylomer® layer to isolate mid-high frequencies that could travel through the coil spring.
These mounts are equipped with different types of coil springs to suit different loading applications from 5 to 60 Kg per hanger.
