Two Stage One Motor Fixed Speed Screw Air Compressor
Two Stage One Motor Fixed Speed Screw Air Compressor uses one drive to power both low-pressure and high-pressure rotors, optimizing pressure division and cutting transmission loss. Without VFD components, this fixed-frequency configuration features fewer vulnerable parts and outstanding stability for constant air consumption. Its synchronized rotor structure reduces extra vibration, achieving low-noise running. It is a reliable high-efficiency option for workshops with stable, continuous compressed air demand.
Advantages of Two Stage One Motor Fixed Speed Screw Air Compressor
Key Advantages
- Strong stability: The mature fixed-frequency design matches the integrated single-drive rotor assembly. With fewer transmission links and no variable-frequency electronic components, it avoids frequency conversion-related failures and supports long-time continuous steady operation under constant air demand.
- High efficiency and energy saving: Its exclusive two-stage single-drive structure shares one power source to drive low-pressure and high-pressure rotors synchronously. It optimizes pressure ratio distribution and reduces transmission loss, delivering sustained high efficiency under fixed rated working conditions, outperforming single-stage and separately driven fixed-frequency models.
- Low noise and light sound: The synchronous single-drive rotor layout eliminates extra vibration from independent driving sets. Coupled with precision rotor balancing and damping bases, it suppresses mechanical resonance and running noise effectively during fixed-speed operation.
