Pneumatic board PB Series (Board type vibration isolator)

Compact size convenient to carry.
Recommendable for a person easy to reduce simple vibration.
Board type vibration isolator small enough to use limited place.

Showa Science’s Board type vibration isolators are 8 line-upped for your budget and usage.

If you have only an air supply, the board is automatically maintained horizontal with air springs.

You need not worry about the levelling, and you can concentrate your efforts to your research or measurement.

For users who need not air supply, we prepare simple use air shielding types, maintenance-free spring types, and high performance rubber types.

You can select among PB series according to the size and weight of the apparatus you are going to load.
