Product Introduction
Permanent magnet variable frequency screw air compressor is a screw air compressor that combines permanent magnet synchronous motor and variable frequency speed regulation technology, with the characteristics of high efficiency, energy saving and stability.
Product Features
1. High Efficiency and Energy Saving
Permanent magnet motors are 10%-15% more efficient than conventional asynchronous motors. Inverter technology eliminates no-load losses, resulting in 20%-40% overall energy savings.
Automatically adjusts speed based on gas demand (e.g., 30%-100%).
2. Stability and Reliability
Inverter soft start reduces grid impact and extends equipment life.
Permanent magnet motors are maintenance-free and quieter.
3. Intelligent Control
Integrated PID control monitors parameters like pressure and temperature in real time to maintain constant gas pressure (e.g., ±0.1 bar).
Supports remote monitoring and fault warnings.
4. Wide Operating Range
Highly efficient even at low loads, suitable for applications with fluctuating gas demand (e.g., factories, textiles, and automotive manufacturing).

Product Applications
• High-energy-consuming industries
fields requiring continuous air supply, such as injection molding, metallurgy, chemicals, and pharmaceuticals.
• Fluctuating air usage
spray painting and assembly lines in automotive manufacturing, where air consumption fluctuates significantly.
• Environments requiring high noise levels
hospitals, laboratories, etc.
FAQ
Q1. What is a permanent magnet variable frequency screw air compressor?
A: • Permanent magnet motor: Utilizes a permanent magnet synchronous motor (PMSM), offering high efficiency (IE4/IE5 class), high starting torque, and significant energy savings.
• Variable frequency drive: The inverter adjusts the motor speed to match actual air demand, eliminating no-load energy consumption.
Q2. What are its advantages over conventional screw compressors?
A: • Energy savings: Variable frequency drive can save 30%-40% in electricity (especially in scenarios with large fluctuations in air demand).
• Low noise: Variable frequency soft start reduces mechanical shock and ensures smoother operation.
• Constant pressure air supply: Minimizes output pressure fluctuations (±0.1 bar), improving process stability.
• Long life: Reduces wear on the motor and main unit caused by frequent starts and stops.
Q3. How should I select a permanent magnet variable frequency air compressor?
A: • Air displacement (m³/min): Based on actual air demand + a margin (recommended 15%-20%).
• Operating pressure (bar): Select according to the equipment's maximum required pressure (7-13 bar is common for single-stage motors).
Q4. Will permanent magnet motors demagnetize? How can this be prevented?
A: • Demagnetization risk: High temperatures (>150°C), overload, and current harmonics can cause demagnetization.
Preventative measures:
• Ensure the cooling system (air/water cooling) is operating properly.
• Avoid prolonged overload operation.
• Choose a high-quality inverter to reduce current harmonics.
Q5. What should I pay attention to during daily maintenance?
A: • Regularly replace: air filter, oil filter, and lubricating oil (recommended every 2000-4000 hours).
• Heat dissipation inspection: Clean dust from the cooler and ensure proper ventilation.
• Electrical inspection: Tighten cable connectors and monitor inverter status.
• Condensate drainage: The air receiver and dryer should be drained regularly.
Q6. Are variable frequency air compressors suitable for all scenarios?
A: • Suitable for applications where gas consumption fluctuates significantly, constant pressure gas supply is required, and electricity costs are high (such as injection molding, textiles, and food).
• Not suitable for applications where gas consumption is extremely stable and the environment is dusty or high temperature (which may affect the life of the inverter).
