Low frequency vibration isolator for weight loads from 15 to 130 lbs. and 1/2 Hz performance vertical and horizontal.
Minus K’s LC-4 is an ultra compact, low-frequency negative-stiffness isolator. It comes in two configurations, our low horizontal frequency performance of 1.5 Hz or our ultra low horizontal frequency performance of 0.5 Hz. Both configurations offer our signature 0.5 Hz vertical natural frequency.
The LC-4 isolators can be combined into multi isolator systems to support heavier payloads while taking up very little room themselves. The isolators are passive, manually-adjustable and require no air or electricity.
If needed, the LC-4 isolators can be customized to achieve user specific needs. Eg., different horizontal and vertical frequencies, damping, etc. They can also be made cleanroom and vacuum compatible.
The curves below shows the 1/2 Hz performance of the LC-4. It offers 10-100 times better performance than an air table.
