BiAir^®-ED-AL – Membrane air spring insulator in anodised aluminium

Bilz BiAir^® Membrane air springs are available in many different sizes, depending on your application. The vertical natural frequency is approximately 2.5 Hz, the horizontal natural frequency approximately 2.8 Hz.

Variants with a nose for mounting valves (MPN) or displacement sensors are available with the hose connection on the left (NL) or on the right (NR).

We would be happy to advise you. Here you can find your contact person.

All information can be found in our catalog excerpt “BiAir® Membrane Air Springs” (PDF).

Mechanical pneumatic level control MPN

A simple, but effective and precise solution is the mechanical pneumatic proportional valve MPN-PVM. The level is continuously sensed using the plunger. The position of the plunger is directly applied to the slide valve and the air spring is either pressurized or vented.

At least three air springs are controlled. If more insulators are required due to reasons of design or load, the system must still be worked in three controlled groups, as otherwise the system is statically overdetermined. This is achieved by using multiple insulators in parallel as a group. An additional air maintenance unit is installed upstream of the control valves to prepare the compressed air.

MPN-LCV	MPN-PVM

Very robust galvanised proportional valve. Level accuracy is approximately ± 1/10 mm.	High-precision chromed proportional valve. Level accuracy is ± 1/100 mm.
