Vibration Isolation - Desk Type Isolators

1. Features 1.1 Any Directional Vibration IsolationThe conventional pneumatic isolators have lower efficiency in horizontal vibration isolation than vertical in general. But DAEIL's new isolators provide high performance of all directional vibration isolation through specially designed horizontal vibration removal mechanism. The reinforced thin-wall rolling diaphragms are only 0.7mm thick. 1.2 High DampingAn ideal vibration isolation system should meet high degree of isolation performance with a high level of pneumatic damping efficiency. DAEIL has achieved this by the advanced pneumatic damping techniques. A special orifice built in the pneumatic isolator makes its table top stable very quickly, damping for gross transient disturbances, such as sudden load changes or bumping the top plate during operation. 1.3 New Top PlateDAEIL makes its stiffness higher than the conventional one in order to get higher first resonance frequency and achieved good damping characteristics by damping treatment on the underside of the top plate. For applications requiring the ultimate stiffness, damping & mounting holes, the special honey comb table tops will be specified upon request. 1.4 Top Cover and Work SpaceTop cover and work space are completely separated in function from the isolated top on which precision equipments are placed. The work space in simple and attractive design having a round finish edge is used for various peripherals such as work pieces, monitor, keyboard, etc. if does not require any vibration isolation. 1.5 Self Leveling TopAir-operated system with three finger adjustable height control valves maintains the absolute level of top plate automatically. The standard model maintains height to 1.0mm, the precision model, to 0.1mm  * DVID series are available in a choice of three types of desk isolators; C type for clean room, L type for laboratory and H type for honeycomb top.  2.
