Single-stage Permanent Magnet Variable Frequency Screw Air Compressor75KW100HP8Bar LUOYOU

It is mainly composed of components such as the main engine, motor, cooling system, intake valve, and exhaust pipe. The main engine adopts a new generation of screw profile, and the lubricating oil quantity for the bearings and the compression chamber has been precisely calculated. The motor is a high-efficiency permanent magnet motor, which has the advantages of low cogging torque and high overload capacity. The cooling system usually employs an aluminum finned cooler with an increased heat transfer area and a high-efficiency axial flow fan. The intake valve is an integrated intake valve with a streamlined flow channel design. The diameter of the exhaust pipe of the machine body has been increased.

Product Overview


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.


Product Specifications


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.




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.



Automotive Assembly: Powers paint booth ventilation systems, pneumatic welding tools, and conveyor belt actuators in car manufacturing plants, ensuring consistent airflow for quality control and worker safety.

Construction: Supports concrete mixing equipment, pneumatic rock drills, and dust collection systems on job sites, with IP54 protection ensuring reliability in dusty, wet conditions.

Mining: Delivers ventilation air to underground mines and powers pneumatic ore conveying systems, with rugged construction resisting the harsh conditions of mining environments.

Textile Industry: Maintains constant airflow for weaving machines, spinning equipment, and fabric drying systems, ensuring uniform fabric quality by preventing pressure fluctuations that cause material defects.
