The DVIA-U Series is a modular, low profile, active vibration isolation platform,
designed to support various sizes and shapes of equipment.
Low-Frequency Vibration Isolation
The advanced active vibration isolation algorithms allow the DVIA-U starts to isolate at 0.5 Hz,
delivering ≥90% vibration isolation at ≥4 Hz.
Modular Architecture
Active Isolation Platform
The DVIA-U Series is a modular, low profile, active vibration isolation platform that can be directly installed
beneath various sizes and shapes of equipment.
No Air
All the DVIA-U requires eletricity to operate.
UI Software for Users
We take pride in our work to provide a vibration isolation system that actually reduce floor vibrations.
The UI software is provided along with the DVIA-U series for users to monitor the real-time active
vibration isolation performance and floor vibration levels.
Feedback & Feedfoward Control Algorithm
The DVIA series uses the Feedback control algorithm to continuously detect vibrations disturbing an isolated
surface and instantaneously react to minimize the vibrations in real-time. The Feed-Forward control algorithm
is employed in the DVIA Series to filter out floor vibrations in advance before the floor vibrations can be
transmitted to equipment installed on the active vibration isolation systems.
Active Vibration Isolation in
All Six Degrees of Freedom
The DVIA Series controls vibrations in three translational degrees of motions
( X, Y and Z) and three rotational degrees of motions ( pitch, roll and yaw).
≥90% vibration isolation at ≥4 Hz.
