RISAN RS-20E Permanent Magnet Variable Frequency Screw Air Compressor

Smarter Energy Saving, Stable Performance, Lower Operating Cost

The RISAN RS-20E Permanent Magnet Variable Frequency Screw Air Compressor is designed for businesses that demand high efficiency, stable pressure, and long-term cost savings. Built with advanced permanent magnet technology, this model delivers reliable compressed air while significantly reducing energy consumption.

🔧 Why Choose RS-20E?

1. Intelligent Energy Saving Control

Unlike ordinary air compressors, the RS-20E uses variable frequency control to automatically adjust output based on actual air demand.

• Ordinary compressors frequently switch between loading and unloading
• Pressure often fluctuates up to +1.5 bar above required level
• This results in extra 10.5% power consumption

With RS-20E:

• Maintains stable pressure at required level
• Avoids unnecessary pressure increase
• Saves about 7% energy for every 1 bar pressure reduction

👉 Result: Lower electricity bills + smoother operation

2. Energy Saving by Constant Pressure

The RS-20E ensures continuous and stable air supply, eliminating inefficiencies caused by pressure fluctuation.

• Traditional compressors consume up to 45% energy even when idling
• RS-20E reduces idle running through smart control
• No more repeated load/unload cycles

✅ Benefits:

• Reduce power waste
• Extend machine lifespan
• Improve production stability
• Protect downstream equipment from pressure shock

⚡ Key Advantages

• ✔ Permanent Magnet Motor – higher efficiency & lower heat loss
• ✔ Variable Frequency Drive (VFD) – smart energy adjustment
• ✔ Constant Pressure Output – stable and reliable performance
• ✔ Lower Maintenance Cost – less wear & tear
• ✔ Long Service Life – optimized running condition
