Combined Rubber-Airspring-Insulator FAEBI ® - HD with adjustable dampening FAEBI ® - HD 22 Rubber air-spring insulator FAEBI ® -HD is made of a combination between high-grade elastomer and metal with an amplified sidewall. In order to obtain as high a dampening effect as possible, the air space is split into two chambers (load / dampening volume) linked by an air pipe. By the adjustable valve the dampening can be changed easily from outside. Due to the friction caused by the air-stream passing through the bypass valve, it is possible to adapt the dampening to each application. Because of the very high dampening, the resonance amplitude is much smaller and therefore you are able to achieve less machine movement. (see graph 1a + 1b) Furthermore the increased transformable energy takes effect on the production quality of your machinery. Note: In contrast to viscous dampers, the air dampening is absolutely wear- resistant and free of maintenance. Furthermore it is possible to change the dampening from outside.
