Frequently Asked Questions
1. What pressure range does this medium-pressure screw air compressor support?
This series is designed for medium-pressure applications, with a rated pressure range of approximately 2.0–3.0 MPa. It is suitable for industrial processes that require higher pressure than standard 7–10 bar compressed air systems.
2. What is the air delivery range of this compressor?
Depending on the model, the free air delivery ranges from 3.5 to 50 m³/min, or approximately 124 to 1,766 CFM. This allows the series to cover both medium-capacity and large industrial air demand.
3. What are the advantages of using a PM VSD screw air compressor?
The permanent magnet variable speed drive helps the compressor adjust output according to actual air demand, reducing unnecessary energy consumption. Compared with traditional fixed-speed or piston compressors, it can also provide smoother operation, lower maintenance requirements, and more stable continuous air supply.
