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.
Flödesförstärkare ökar cylinderhastigheten genom att använda tryckluft för att dra in ytterligare atmosfärisk luft i systemet, vilket effektivt multiplicerar tillgängliga flödeshastigheter med 2-5 gånger utan att kräva större kompressorer, vilket möjliggör snabbare cykeltider och förbättrad produktivitet i pneumatiska applikationer.

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 effect1, 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
- Tryckskillnad: High-velocity compressed air creates low pressure zones
- Atmospheric entrainment2: Vacuum effect draws in free atmospheric air
- Flow multiplication: Total output flow exceeds input compressed air flow
- Energibesparing: System efficiency improves through atmospheric air utilization
Internal Design Components
Precision-engineered components optimize the Venturi effect for maximum flow amplification.

| Primary nozzle | Accelerates compressed air | Converging-diverging profile3 | Creates maximum velocity |
| Mixing chamber | Combines air streams | Optimized length and diameter | Ensures complete mixing |
| Secondary inlet | Admits atmospheric air | Large cross-sectional area | Minimizes restriction |

Flow Amplification Ratios
Different amplifier designs achieve varying levels of flow multiplication.
Typical Amplification Factors
- Standard amplifiers: 2:1 to 3:1 flow multiplication
- High-performance units: 4:1 to 5:1 amplification ratios
