Low Freq. Pneumatic Levelling Mounts

Easy to use, wide selection

Pneumatic Leveling Mounts
Natural frequency 3 Hz to 10 Hz

Extremely low natural frequency of only 3 Hz: With the PLM product family, ACE can now offer low frequency vibration and impact isolation for many applications. There are eight different, readily available off-the-shelf designs, which can withstand small to large loads from 100 lbs up to 19,200 lbs (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 leveling via the integrated valve. When used as a vibration absorber, the internal air chamber provides a significant isolating effect, starting at 5 Hz. The ratio of horizontal to vertical natural frequency is 1:1 and only 3.0 Hz in optimally loaded conditions.
