Pneumatic Air Spring Elements
Natural frequency 3 Hz to 10 Hz

Extremely low natural frequency of only 3 Hz: With the air spring elements of the product family PLM, ACE can now offer low frequency vibrations and impact isolation to many sectors. There are eight different, readily available off-the-shelf designs, which can withstand small to large loads from 45 kg up to 8,800 kg. They enable all types of equipment to be isolated from undesirable vibrations and at the same time can be used for perfect levelling via the integrated valve. When used as a vibration absorber, the internal air chamber provides a significant isolating effect, starting at 5 Hz and up. The ratio of horizontal to vertical natural frequency is 1:1 and only 3.0 Hz in optimally loaded conditions.

General information

Application Examples

Low Freq. Pneumatic Levelling Mounts - PLM
In an opera production a 3D HDD projector was supposed to project images onto the stage during performances. Standing as it did on a trolley, which was to be moved over a tiled floor, the projector was virtually unusable. The problem was solved by...
Low Freq. Pneumatic Levelling Mounts - PLM
At a renowned Belgian chocolatier, part of the production process led to vibration and oscillation in an adjacent house. Despite numerous tests, the manufacturer was unable to find a solution that could isolate vibrations below 20 Hz, until they...
Low Freq. Pneumatic Levelling Mounts - PLM
A university of applied sciences team optimises oil pumps to reduce the fuel consumption of combustion motors. Numerous tests are necessary for this. A test stand caused undesired vibrations. PLM air spring elements from ACE ensure damping at...
