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-8 bench top platform offers 10-100 times better performance than a full size air table in a package only 4.6 inches tall. This is the thinnest, most portable, and most user-friendly isolator ever offered that is capable of delivering this level of performance. 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 isolation.
The BM-8 is excellent cost effective bench top isolator for payloads loads up to 250 lb. and 1/2 Hz performance vertical and 1 1/2 Hz horizontal.
