Featuring our unique Stabilizer™ hybrid chamber design, these isolators offer the largest compliance volume, and therefore the best vertical isolation of any compact isolators. The extremely low profile design allows integration into a large variety of small machines. Automatic releveling maintains platform stability. The CM-225 is also available in an Ultra-Clean version (UCM-225) for use in cleanroom environments. The UCM-225 has been tested to cleanroom Class 10 compatibility. • Integrated leveling valves maintain platform leveling while providing fast response to load changes • Self-centering piston eliminates horizontal isolation shorts • Low profile allows easy integration into small systems Specifications CM-225 Isolation Performance Model Vertical Isolation* Horizontal Isolation* Amplification at Resonance Maximum Load per Isolator [lb (kg)] Re-leveling Accuracy [in.
