DVIM-G
DVIM-G Series

Advanced Vibration Isolator

The DVIM-G Series serves as the flagship pneumatic isolation system within the DVIM lineup. Optimized for high-precision metrology and inspection equipment with moving payloads, it combines superior isolation efficiency with high-damping mechanics. This design drastically minimizes settling time, ensuring maximum throughput and measurement accuracy.

Features

Dual Chamber Damping System

The DVIM-G Series employs a sophisticated Dual Chamber System designed to neutralize the destabilizing effects of moving payloads. By linking distinct air and damping chambers through a precision network of internal and variable external orifices, the system strictly regulates airflow to dissipate kinetic energy generated by stage acceleration. This mechanism creates a rapid restoring force that significantly reduces settling time, while the variable external orifice allows operators to fine-tune the damping response to match specific application requirements.

Gimbal Piston: True Omnidirectional Isolation

Standard pneumatic isolators effectively manage vertical gravity loads but often fail to block horizontal disturbances like traffic or structural sway. The Gimbal Piston overcomes this limitation using a low-friction inverted pendulum mechanism. This design decouples the payload from the ground, allowing the support column to swivel freely. When the floor shifts horizontally, the isolator yields, preventing vibration transfer and ensuring absolute stability for your equipment.

Superior Low-Frequency Isolation

Achieve optimum stillness with our advanced mechanical filter system and proprietary isolator design. The DVIM-G Series effectively lowers the system's resonant frequency, delivering 80-90% vibration isolation at 5 Hz. This capability is critical for eliminating floor vibration noise that compromises high-resolution imaging and measurement.

Designed for Moving Stages

For applications involving moving linear stages, the DVIM-G Series integrates external oil dampers. These dampers are essential for absorbing acceleration forces and minimizing settling time. While higher damping naturally results in a slight increase in resonant frequency, this configuration is deliberately optimized to prioritize dynamic stability and throughput for moving payloads.

High-Precision Leveling for Higher Stability

Maintain exact stability with our high-performance leveling valves. For critical applications, our optional Precision Leveling system delivers ±0.05 mm repeatability. This ultra-tight tolerance minimizes settling time, ensuring your equipment returns to absolute equilibrium instantly after high-speed motion.

Options

External Oil Damper

External Oil Damper

This option integrates a viscous oil damping mechanism to counteract the forces generated by moving payloads. It is specifically engineered to minimize stage motion amplitude and shorten settling time. While standard pneumatics isolate floor vibration, the External Oil Damper ensures positional stability during aggressive machine operations.

Air Operated Valve

Air Operated Valve

Minimizing settling time requires rapid system reaction. The Air Operated Valve is engineered to regulate airflow significantly faster than standard valves, eliminating latency during dynamic events. By increasing the response speed of the pneumatic isolators and leveling valves, it allows the system to counter linear stage motion instantly, restoring stability and equilibrium with maximum efficiency.
