Air spring isolators provide an effective alternative to traditional steel springs for reducing vibration, shock and structure-borne noise.
Bilz offers two main solutions: FAEBI® Rubber Air Springs and BiAir® Low Frequency Membrane Air Springs.
FAEBI® Rubber Air Springs
FAEBI® air springs use a reinforced elastomer design that combines vibration isolation with high mechanical stability.
Key Benefits
- Integrated damping
- Adjustable air pressure for changing loads
- Reduced transmission of structure-borne noise
- Anti-slip base pads
- Optional mechanical level control
Typical Applications
FAEBI® air springs are suitable for:
- High-speed presses
- Forging hammers
- Machines with dynamic forces
- Measuring and testing equipment
- Precision machine tools
BiAir® Low Frequency Membrane Air Springs
BiAir® isolators use a flexible rolling membrane and a two-chamber air system with adjustable damping.
They are designed for applications requiring very effective low-frequency vibration isolation.
Key Benefits
- Automatic level control
- Adjustable damping
- Consistent isolation under changing loads
- Reduced structure-borne noise
- Protection against excessive pressure or piston travel
Typical Applications
BiAir® systems are suitable for:
- Precision measuring equipment
- Testing systems
- Laser equipment
- Optical and electronic instruments
- Precision finishing machines
- Engine and gearbox test stands
- Machine foundations
FAEBI® or BiAir®?
The correct choice depends on the machine, vibration frequency, load conditions and required isolation performance.
FAEBI® is well suited for dynamic machinery and general vibration isolation, while BiAir® is ideal for highly sensitive applications requiring low-frequency isolation and automatic level control.
Bilz can help determine the most suitable air spring solution for your equipment and operating environment.
