Features of Medium and High Pressure Screw Rotary Air Compressor

1. Two-stage booster, high efficiency & energy saving: Integrated two-stage rotor design gradually increases pressure, reducing single-stage compression losses and improving overall energy efficiency.
2. High exhaust pressure: Delivers up to 4.0MPa, suitable for high-pressure industrial applications.
3. Imported integrated head, durable: High-precision, imported integrated head with optimized structure improves compression efficiency and extends service life.
4. Fully synthetic lubricant, low maintenance costs: Utilizes high-performance synthetic lubricant to reduce wear, lower oil consumption, enhance reliability, and reduce maintenance costs.
5. Intelligent control system: User-friendly interface with automated controls, remote monitoring, and self-diagnostics for efficient, safe operation.
6. Multiple cooling options: Air-cooled and water-cooled systems available for different environments, ensuring long-term stable operation.

Working Principle

1. First stage compression: Air enters the low-pressure screw rotor, is compressed to intermediate pressure, and then cooled by a high-efficiency intercooler to minimize energy loss.
2. Second stage compression: Air proceeds to the high-pressure screw rotor for further compression, reaching the set high-pressure range (1.8MPa~4.0MPa).
3. Oil-air separation: The compressed air passes through a separation system to remove impurities and oil, delivering clean, stable air suitable for direct use by production equipment.
4. Optimized two-stage design: Reduces energy consumption, controls temperature rise, and ensures efficient, stable long-term operation.
