Low Frequency Vibration Isolation with PLM Pneumatic Levelling Mounts

When precision and vibration control are essential, ACE's PLM series of Low Frequency Pneumatic Levelling Mounts offer an ideal solution. With a remarkably low natural frequency of just 3 Hz, these air spring elements effectively isolate even the most sensitive equipment from disruptive vibrations. Designed for use in high-precision environments, PLM elements are available in eight models, handling loads from 45 kg to 8,800 kg—making them a versatile choice for both lightweight instruments and heavy machinery.

PLM mounts combine excellent damping performance with easy adjustability. Each mount features an integrated valve, enabling precise levelling of equipment. This combination of vibration isolation and levelling is particularly beneficial for measuring tables, test stands, high-speed presses, and production lines where mechanical stability and accuracy are vital. Thanks to the internal air chamber, PLM mounts begin providing isolation from as low as 5 Hz, with optimal performance around 3 Hz under ideal load conditions.

Proven in Practice: Real-World Applications

ACE’s PLM pneumatic levelling mounts have proven their effectiveness across a wide range of demanding applications. In a Belgian chocolate factory, 14 PLM-3 units reduced disruptive low-frequency vibrations by 80%, restoring peace in nearby residential areas. At an opera house, PLM-1 mounts stabilized a high-performance 3D projector on a mobile trolley, eliminating vibrations from tiled flooring and ensuring flawless visuals. In a university lab, PLM elements were used to isolate pump test stands, significantly improving the accuracy of fuel-saving experiments for combustion engines. Even in the high-end audio sector, PLM-1 mounts are integrated into hi-fi racks to eliminate ambient disturbances, delivering pristine sound quality. These examples highlight the versatility and precision of ACE’s low-frequency air spring systems in delivering exceptional vibration isolation where it matters most.
