Type JM3 seismic VibrationIsolator
The Type JM3 seismic vibration isolator is specifically engineered for light to medium-duty equipment in seismic zones. It combines the benefits of vertical vibration isolation with basic seismic restraint. Designed with a compact structure and color-coded spring options, JM3 offers stable performance and easy installation for small HVAC units, fans, pumps, and compressors.
This model features a fixed working height and a top-mounted adjustment bolt, making it ideal for applications where space is limited but seismic performance is required.

What equipment is JM3 seismic vibration isolator best suited for?
Small centrifugal fans
Wall-mounted or base-mounted pumps
Compact chillers or condensing units
Air compressors
Fan coil units or terminal devices
Installed in mechanical rooms or rooftop HVAC systems
How does the JM3 isolator provide seismic protection?
Though compact, the JM3 includes directional restraints that limit lateral movement during seismic events. Its spring structure isolates vertical vibrations, while its frame design prevents displacement — ensuring your equipment stays stable during shocks and vibrations.
How does the JM3-A Type Single-Spring Vibration Isolator Effectively Reduce Vibration and Noise During Machine Operation?
The JM3-A type single-spring vibration isolator features a unique design that combines a rubber cap with a steel outer shell to effectively absorb and isolate vibrations from machine operation. This isolator significantly reduces vibration and noise during equipment operation, enhancing stability and comfort. It is especially suitable for machinery that needs to run continuously for long periods, helping to extend equipment lifespan and improve the working environment.
Why Choose the JI3-A Type Spring Vibration Isolator with Transport Protection Bolts to Enhance Transport Safety?
The JI3-A type spring vibration isolator is equipped with specially designed transport protection bolts that lock the isolator in place during transport. This feature prevents the equipment from shaking during transit, thus avoiding potential damage to connection parts. Whether for domestic or international shipments, this protection ensures the safety of the equipment during transport and minimizes the risk of transport-related damage.
Is the Installation and Maintenance of the JM3-A Type Single-Spring Vibration Isolator Easy?
The JM3-A type single-spring vibration isolator is designed for easy installation, requiring no complex tools. Users can quickly install it and get it into operation. The transport protection bolts can simply be removed after the equipment reaches its destination. Additionally, the isolator is low-maintenance, requiring only regular checks and cleaning to ensure long-term efficient performance, reducing both maintenance costs and operational complexity.
