This is an industrial-frequency screw air compressor with a rated power of 315 kW. It employs a two-stage compression unit. After the first stage of compression and intermediate cooling, the air enters the second stage, where it is further compressed to the required pressure. The motor operates at a fixed speed and is not adjustable.

Product Features and Advantages
1. Efficient and Reliable
Utilizing two-stage compression technology, the two stages share the pressure ratio, resulting in lower loads. The mechanical efficiency and reliability are far superior to those of single-stage inverters of the same power, while also being more energy-efficient than conventional single-stage units.
2. High-Flow Stable Output
As a fixed-speed (industrial frequency) unit, it operates at rated speed even under load, continuously providing a large and stable supply of compressed air.
3. Rugged and Durable Structure
Designed for heavy-duty continuous industrial operation, the core components are robust and have a long lifespan.
4. Low Initial Investment Cost
Compared to permanent magnet inverter units of the same power, the unit offers a more competitive purchase cost and a relatively low maintenance threshold.
Application Industries
• Large-scale metallurgy and foundry: steel mills, non-ferrous metal smelting, and forging workshops.
• Mining: Powering large rock drills and pneumatic equipment.
• Chemical and fertilizer: Process air and instrument air for large chemical plants.
• Cement and glass manufacturing: Powering the production process.
• Centralized air supply stations: Serving as the primary base unit in air compression stations, this unit handles the most basic air demand.
