The NV150 air-springs are the pneumatic isolators for the cplusw damping tables and are inserted into their base frame. But as an OEM-product the NV150 can be used in many ways. Because of an upper stopper of the piston the design offers a maximum safety against an accidentally compression overload. A permanent supply of compressed air is necessary for operation as well as a compression or rather a height controller for setting up the working height in between the levelling range of +/- 4mm The resonance frequency is about 1,7 Hz in horizontal directions and in vertical direction under 2,5 Hz. CplusW offers support for system integration into customer products or special applications. Sets composed of three, four or even more NV150 air-springs will be delivered with the necessary number of height controllers HR2. NV150 systems do not need any special maintanance after the initial setup.
