Permanent magnet variable frequency single-stage screw air compressor is a high-efficiency air compressor that combines permanent magnet synchronous motor, variable frequency drive technology and single-stage screw compression structure.
Features of Permanent Magnet Variable Frequency Air Compressors
1. High Efficiency and Energy Savings
The permanent magnet motor and variable frequency technology combine to achieve 20%-40% energy savings (compared to fixed-speed compressors with standard frequency).
Especially suitable for fluctuating air demand (avoiding losses from frequent loading and unloading).
2. Precise Pressure Control
The variable frequency drive responds to pressure signals in real time, ensuring air pressure fluctuations within a range of ≤0.1 bar, improving process stability.
3. Low Maintenance
The single-stage screw structure simplifies mechanical design and reduces potential failure points; the permanent magnet motor eliminates carbon brush wear.
4. Low-Noise Operation
Variable frequency technology eliminates high-speed idling, reducing average noise levels by 3-5 dB(A).
