Furthermore, air springs are the only passive isolator that can achieve a reduction in the natural frequency. What makes air springs useful in many applications is that they are the only passive isolator that operates on the principle of compressing a gas rather than deflecting a solid.Īir springs are therefore the passive isolator with the lowest natural frequency, and the lower an isolator’s natural frequency, the better the isolation effectiveness. These latter, doughnut-shaped, convolutions may be stacked one, two or three high depending on the performance required. These bellows can be tubular, or come in convoluted shapes. But while many people know that air springs often provide the ultimate ride in stretch limos, luxury coaches and high-speed trains, not all are aware of their extensive applications in materials handling machinery.Īpplications range from isolating heavy equipment for operational efficiency (conveyors, generators, compressors and vibrating screens) through to protecting of delicate equipment.Īir Springs are in essence immensely strong rubber and fabric-reinforced balloons or bellows.
