Description
Minus K isolators, they are completely passive and require NO AIR or ELECTRICITY. There are no computers, compressors or air lines needed or that can breakdown. The WS-4 Compact Vibration Isolation Table offers better performance than a full size air table. The table come in several capacity ranges to match your vibration-sensitive instruments.
If needed, the 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
Minus K manufactures vibration isolators that employ Negative-Stiffness technology in low-frequency vibration isolation. These mechanisms compress the internal springs, flexures and columns to completely mechanical vibration.
The WS-4 is a cost effective product for weight loads up to 1000 lb. and 1/2 Hz performance vertical and horizontal.
