Designed to excel in low-pressure industrial applications that demand high-volume airflow with minimal energy waste, our Single stage PM VSD Screw Air Compressor merges cutting-edge permanent magnet motor technology with variable speed drive (VSD) to deliver unprecedented 30–50% energy savings compared to traditional fixed-speed compressors. Its innovative large rotor design (with a 5:6 tooth ratio) and low-speed operation (1450 RPM) minimize noise, vibration, and wear, ensuring stable airflow for continuous industrial processes.
This compressor is engineered for versatility, supporting a wide range of industries from automotive manufacturing to mining, where reliable low-pressure air supply is essential for equipment performance and operational efficiency. The integration of smart controls and durable components ensures consistent performance even in dusty, high-temperature environments, making it a cost-effective solution for both indoor factories and outdoor job sites.
Pressure Range: Optimized for 0.21–0.3 MPa (3–4.35 psi) applications, ideal for high-volume, low-pressure needs such as ventilation, pneumatic conveying, and large-scale tool operation.
Flow Rate: Delivers robust airflow from 7.16 m³/min (253 CFM) in 90kW models to 70.23 m³/min (2479 CFM) in 200kW units, ensuring sufficient capacity for multi-machine production lines.
Motor: Features an IE5-rated PM motor—the highest efficiency class available—with IP54 protection against dust and water, paired with F-class insulation to withstand 180°C heat without performance loss.
Noise Level: Operates at ≤68 dB thanks to a sound-dampening enclosure and low-vibration rotor design, meeting strict workplace noise regulations and reducing operator fatigue.
Cooling: Reliable air-cooled system with a high-capacity radiator, tolerating ambient temperatures up to 46°C—perfect for hot industrial environments or outdoor installations.

Cooling: Reliable air-cooled system with a high-capacity radiator, tolerating ambient temperatures up to 46°C—perfect for hot industrial environments or outdoor installations.
Dynamic Pressure Control: The VSD adjusts motor speed in 1 second to match real-time airflow demand, reducing 15–20% no-load energy loss that plagues fixed-speed compressors during idle periods.
Durable Design: Built with a heavy-duty cast iron housing, precision-machined rotors, and premium SKF bearings, ensuring a 100,000-hour lifespan with minimal wear, even under continuous operation.
Low Vibration: The large rotor design with optimized tooth geometry minimizes air pulsation, reducing stress on downstream pipes, valves, and tools, thereby extending their service life by up to 30%.
Plug-and-Play Installation: Comes pre-equipped with a cyclone separator (to remove moisture and particulates) and low-pressure cooler, simplifying setup and enabling quick integration into existing systems.
IoT Integration: Optional cloud-based monitoring platform provides real-time analytics on energy usage, pressure stability, and maintenance needs, allowing managers to optimize performance and reduce operational costs.
