What Are Vibration Isolators?
Vibration isolators are specialized devices designed to reduce or block vibrations transmitted between two surfaces or components. They act as buffers between machines and their mounting structures, absorbing and dampening mechanical energy to prevent noise, damage, or performance loss.
In simpler terms, vibration isolators make sure that the energy created by a vibrating machine doesn’t transfer to its surroundings — protecting sensitive equipment, reducing noise, and extending service life.
How Do Vibration Isolators Work?
The principle behind vibration isolators is rooted in mechanical resonance and damping. Every machine generates vibrations at a certain frequency. When that frequency matches the structure’s natural frequency, resonance occurs — amplifying vibration.
Vibration isolators are designed to shift the resonant frequency and absorb excess energy, using materials like rubber, springs, or air cushions. The result is smoother operation and a quieter environment.
Importance of Vibration Isolation in Modern Engineering
Uncontrolled vibration isn’t just noisy — it’s destructive. Over time, it can loosen fasteners, wear out bearings, and even cause structural cracks. In industries like aerospace or healthcare, where precision is crucial, vibration isolation becomes essential.
By using vibration isolators, engineers can:
- Reduce machine wear and tear
- Minimize structural fatigue
- Improve accuracy of sensitive instruments
- Enhance comfort and safety
Types of Vibration Isolators
Spring Mounts
Spring mounts are heavy-duty vibration isolators designed to support equipment like pumps, compressors, and AHUs that sit directly on the floor or a frame.
They consist of steel springs encased in a housing that allows vertical deflection to absorb mechanical vibrations effectively.
Spring mounts are ideal for machines that generate low-frequency vibrations, offering both stability and flexibility.
Common Uses:
- AHUs and FAHUs on building rooftops
- Chilled water pumps in mechanical rooms
- Compressors and large blowers
Spring Hangers
Spring hangers are used to suspend equipment or ductwork from ceilings while isolating vibrations transmitted through the structure.
Each hanger includes a coil spring and rubber insert that absorbs both vertical and lateral movements, ensuring minimal vibration transfer.
Common Uses:
- Hanging AHUs or duct systems from beams
- Suspended pipelines and fan coil units
- Vibration-sensitive ceilings in HVAC systems
Combination Hangers
Combination hangers merge the benefits of spring hangers and rubber isolators into a single unit.
They include both a rubber element for high-frequency vibration control and a spring section for low-frequency absorption.
This hybrid design provides superior vibration damping in dynamic environments where equipment is mounted above occupied spaces.
Common Uses:
- FAHUs and exhaust fans
- Suspended pumps
- Ceiling-mounted AHUs
House Spring Mounts
House spring mounts (also known as enclosed spring isolators) feature a metal housing around the spring, providing protection and lateral stability.
These are perfect for outdoor or exposed installations where weather resistance and high load capacity are required.
They are widely used for pumps, generators, and rooftop AHUs, offering both vibration control and durability.
Common Uses:
- Outdoor AHUs and FAHUs
- Pump skids and generator sets
- Roof-mounted mechanical units
