There are a variety of isolators available. How do I determine which is best for my use? |

It depends on circumstances particular to the installation. Air isolators yield the lowest natural frequency. Steel springs are next, followed by elastomer pads and isolators. There are other materials available such as felt, cork, fabric and wool, which are used when a stiffer isolator is required. In most cases, an isolator is selected on the basis of natural frequency requirements to give the isolation desired.
Information required before selecting an isolator:- Isolation desired - percent reduction
- Lowest disturbing frequency
- Maximum load per isolator, weight distribution, location of center of gravity.
- Area and location available for isolator
- Height or elevation limitations
- Stiffness of support
- Flexibility of lines to isolated unit
- Allowable motion
- Clearance around isolated unit
- Environmental conditions - such as temperature, acids, solvents, oils, radiation
