Slow cylinder speeds plague manufacturing operations, creating bottlenecks that reduce productivity and increase cycle times. Traditional solutions like larger compressors or bigger valves often prove expensive and impractical, leaving engineers frustrated with inadequate pneumatic performance.
Flow amplifiers increase cylinder speed by using compressed air to draw additional atmospheric air into the system, effectively multiplying available flow rates by 2-5 times1 without requiring larger compressors, enabling faster cycle times and improved productivity in pneumatic applications.
Last month, I helped Michael, a production engineer at an automotive parts factory in Michigan, whose assembly line cylinders were operating too slowly to meet production targets. After installing our Bepto flow amplifiers, his rodless cylinder speeds increased by 300%, allowing his team to exceed their daily quotas.

What Are Flow Amplifiers and How Do They Work?
Understanding flow amplifier technology reveals why these devices deliver such impressive performance improvements.
Flow amplifiers work by using the Venturi effect, where compressed air flowing through a nozzle creates a vacuum that draws in additional atmospheric air, multiplying the total flow volume available to actuate cylinders without increasing compressed air consumption.
The Venturi Effect Principle
Flow amplifiers harness fundamental fluid dynamics to multiply available air flow.
Key Physical Principles
- Pressure differential: High-velocity compressed air creates low pressure zones
- Atmospheric entrainment: Vacuum effect draws in free atmospheric air
- Flow multiplication: Total output flow exceeds input compressed air flow
- Energy conservation: System efficiency improves through atmospheric air utilization
