The BiAir® Membrane Air Spring series is made of turned or cast aluminum. The air space is enclosed by thin-walled flexible and pressure-resistant rolling membrane. A piston sits on top of the membrane and is pressed into the air space.
Highly effective insulation of vibrations and structure-borne noise for a wide variety of machine types, optical and electronic devices, laser systems as well as vehicle, engine and transmission test benches.
Low-frequency air springs from Bilz provide highly effective vibration isolation and can be combined with a variety of mechanical and electronic level control systems.
The damping level of the pneumatic and low-maintenance air springs can be adjusted as required.
The use of Bilz BiAir® air spring isolators with active level control constantly maintains the correct level of machines or foundations. The level control and adjustment is entirely automatic.
The pressure in the air springs is appropriately adjusted by pressurising or venting in response to load changes. This keeps the isolating effect constant in all events.
Unlike steel springs air springs do not transmit structure borne sound.
