The DVIM-F series is a basic pneumatic vibration isolator and its structure consists of bellows air springs.
The DVIM-F isolators are suitable for metrology equipment requiring vibration isolation above 10 Hz.
Exceptional Durability
The DVIM-F pneumatic vibration isolators consist of the bellows air springs which are designed to perform
in the toughest conditions and in the long-term.
Pneumatic Vibration Isolation System
At Reasonable Price
The DVIM-F pneumatic vibration isolators are affordable and can be used in a wide range of applications.
High Performance Leveling Valve
The standard leveling vales with repeatability of ±0.1 mm and the precision leveling valves with repeatability of ±0.05 mm.
The precision leveling valves are recommended if both the releveling accuracy and the settling time are required.
Built-in Oil Damper to Support Metrology Equipment with Linear Stage
The built-in oil dampers are integrated in the DVIM-F series, dampening and minimizing disturbances caused by the linear
stage motions. Unfortuantely, there is a trade-off between the resonant frequency and damping efficiency. As damping is
increased, the fast settling time is acheived however, the resonant frequency of the DVIM-F isolators shift slightly higher
and the efficiencyof vibration isolation performance is decreased.
40 – 50% vibration isolation at 10 Hz

Built-In Oil Damper
Better Stability & Faster Settling Time
The built-in oil damper option is installed with stoppers to limit the linear stage from moving beyond certain stroke range
in the three horizontal directions. The built-in oil damper option provide high level of damping by an oil inside the dampers.
The higher the visocosity of the oil, the stiffer pneumatic vibration isolators which leads to shorten the settling time and
increases the stability of the systembut the transmissibility roll-off rate decreases.
