Airmount® Isolator Advantages

Why use an Airmount isolator, rather than a coil spring or other type of isolator?

Unsurpassed Isolation Capability

Airmount isolators can provide the highest degree of isolation of any type vibration isolator. System natural frequencies as low as 1 hertz are available. The addition of an auxiliary reservoir can provide even lower system frequencies. In order to achieve similar results from a conventional coil spring isolator, a real deflection of 230 mm would be required.


Constant Isolation Efficiency

Airmount isolators are unique in that the system’s natural frequency does not change significantly with changes in load. This unique feature, combined with accurate height control, will allow the use of the same Airmount isolator at each mounting point of an unevenly loaded machine.


Accurate Height Control

Airmount isolators provide accurate height control through regulation of internal air pressure. This feature eliminates the fatigue and permanent set found in the use of other types of vibration isolators.


Wide Size Range

Airmount isolators are capable of isolating loads of 0.44kN per mounting point to over 577 kN per mounting point.


Compact Installed Height

Airmount isolators can carry the loads and provide the isolation described above at installed heights as low as 31m.
Coil springs providing equal isolation would require a free height of 125 mm to 635 mm.


Extended Equipment Life

Airmount isolators extend equipment life through their superior isolation capabilities.


Effective Noise Reduction

Airmount isolators reduce structurally transmitted noise. Airmount isolators are also quiet in themselves, since there is no spring chatter as found in conventional coil springs.


Versatile

Airmount isolators can be used not only to protect structural members from vibrating machinery, but are also widely used to protect delicate equipment from structurally transmitted vibration.

Many of our air springs are also available in high strength construction for higher pressures. Please refer to our selection guide for additional information.
