Self-Leveling Compact Pneumatic Vibration Isolator

Newport CM-225 isolators provide excellent pneumatic vibration isolation for platform loads up to 225 lbs. Featuring our unique Stabilizer™ hybrid chamber design, these isolators offer the largest compliance volume, and therefore the best vertical isolation of any compact isolators. Automatic releveling maintains platform stability.

Integrated fast response leveling valves
Self-centering piston eliminates horizontal isolation shorts
Low profile allows easy integration into small systems

Stabilizer™ Hybrid Chamber Design

Side view of CM-225 isolator

One of the most important design goals of pneumatic vibration isolators is to achieve lower natural frequency. It is related to the isolator's compliance volume - the larger the volume, the lower the frequency. Unlike the conventional design of a compliance chamber (the volume of which affects natural frequency) and a damping chamber, Newport's patented Stabilizer hybrid chamber design consists of a small size initial chamber and a second damping chamber together as a unified hybrid chamber. Because the initial chamber is reduced dramatically in size, it forces the isolator to use the second chamber as part of the compliance volume, which greatly increases the compliance volume for a given package size, and greatly lowers the natural frequency.
