Product Details:

With deep natural frequency & adjustable dampening (pat) for vibration isolation of measuring & testing machines, optical and electronic equipment, laser machines, fine machining plant, vehicle & motor performance testers etc.

Product Description:
The Air Spring Isolator BiAir consists of either a steel or cast aluminum body whose air volume is enclosed by a thin-walled, flexible and pressure-resistant rolling diaphragm. The piston is seated on this diaphragm & is pushed into the air volume.

This design causes highly effective vibration isolation. In order to obtain as high a dampening effect as possible, the air space is split into two chambers (load and dampening volume) that are connected by an air tube. The amount of dampening can be easily changed by the adjustable valve located on the outside of the air spring. As the load on the air spring changes, air is forced through the bypass valve creating friction. This friction creates up to an 18% dampening effect. Additional safety valves protect the rolling diaphragm from getting damaged by over inflation.

Range of Application:
Highly effective vibration isolation of sensitive measuring (CMM) and testing machines, fine machining plant, as well as optical and electronic equipment. Another important range of application is the vibration isolated foundation of vehicle, motor and other performance testers. BiAir Air Spring isolators are extremely well suited for the isolation of foundations e.g. equivalent machine loads. Air springs with higher max. loads as well as air springs with lower natural frequencies can be supplied upon request!

Advantages compared with conventional steel springs:
BiAir Air Spring Isolators with level control are an active system. The machine foundation level consistency will always be preserved! Automatic leveling adjustment.

BILZ level controller systems:
Level control is an important part of an optimally functioning air spring system. The automatic level controller can be utilized to overcome the problem associated with load changes in air spring isolated machines, which can result in tilting of the machine.

The height of the specific elements BiAir or FAEBI can be controlled by changing the air pressure in the air spring isolators. Quick inflation or deflation will hold the machines level even if their center of gravity keeps changing.

Control circuit:
The circuit consists of at least three air springs. If more air springs are needed for structural or loading reasons, the system must always include 3 position points, e.g. three controlled components to avoid being in a statically indeterminate condition . This is achieved by connecting sets of air springs in parallel.
