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 BM-4 bench top platform offers better performance than a full size air table. The isolators 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 offer completely mechanical vibration.
The BM-4 is excellent cost effective bench top isolator for payloads loads up to 200 lb. and 1/2 Hz performance vertical and horizontal.
