One Stage Low Pressure VSD Screw Air Compressor

One Stage Low Pressure VSD Screw Air Compressor

One stage low-pressure variable frequency screw air compressor is engineered for stable low-pressure air supply. It features energy-saving rotor profile to eliminate waste from pressure relief. The intelligent VFD system adjusts speed automatically with air demand, maintaining steady pipeline pressure. Equipped with vibration dampers and soundproof enclosure, it runs quietly. Simple structure brings convenient maintenance and reliable continuous operation, ideal for factory low-pressure pneumatic processes.

Advantages of One Stage Low Pressure VSD Screw Air Compressor

Key Advantages

  • High efficiency & energy saving: Optimized single-stage rotor profile for low-pressure working conditions. It delivers required low-pressure air directly and avoids energy waste from high-pressure relief, cutting no-load loss effectively and saving long-term power costs.
  • Intelligent variable frequency: Adopts PID closed-loop frequency conversion control. It senses real-time pipeline pressure and adjusts rotor speed steplessly according to air consumption, supplying constant-pressure air and reducing impact and energy loss from frequent loading/unloading.
  • Low noise operation: With precisely optimized rotors, vibration-damping base and multi-layer sound insulation enclosure plus low-noise cooling fan, it greatly reduces mechanical vibration and airflow noise for a quieter workshop environment.
