Series BiAir®-ED-HE-MAX in cast aluminium
The BiAir® membrane air spring insulator is made of cast aluminium. The air space is enclosed by a thin-walled flexible and pressure-resistant rolling membrane. The piston sits on the membrane and is pressed into place by the air volume.
This design allows for highly effective vibration isolation. In order to simultaneously achieve the greatest possible damping effect, the interior of the air spring is divided into two air chambers connected by an air hose (load and damping volume). An adjustable throttle valve is used to set the flow cross section to the desired damping effect from the outside. The friction in the air flow generated by the throttle valve can create a damping effect of up to 15 %.
Damage to the rolling membrane due to overpressure is virtually impossible through the use of additional safety valves or a mechanical piston stroke limit.
