The sensitive measurement test benches used at AVL for e-motors and engines require trouble-free operation. Trouble-free here means free mainly free from vibrations. Ultimately, reproducible, consistent test environment conditions need to be guaranteed. AVL approached us for a customised solution for the vibration decoupling of their test bench test plates. After intensive consultation, it became evident: it was a clear case for BiAir®…

Our membrane air spring systems BiAir® with resonant frequency of 2,5-3 Hz is used at AVL for source and receiver isolation with e-motors and engine test benches. These decouple the test bench during test operation and avoid or reduce structure-borne noise and structural movement in the test and research facilities. BiAir® air springs are available with mechanical or electronic-pneumatic level control.

Air springs do not transfer structure-borne noise, have electronic-pneumatic level control, and have versatile uses.

"Bilz has a good reputation in the industry and is an efficient supplier of air spring systems of high quality.
