mobile rotary screw air compressor for construction site

Equipped with a high-efficiency compression system, intelligent control technology, and energy-saving design, this mobile rotary screw air compressor is widely applied in mining, infrastructure construction, tunneling, non-excavation drilling, and more. It delivers reliable, stable air supply even in the most demanding environments.

Features of Mobile Rotary Screw Air Compressor

1. Large exhaust capacity: High single-unit exhaust output reduces the need for multiple machines in parallel, boosting work efficiency and lowering both fuel and transport costs.
2. Intelligent heat dissipation system: Silicone oil frequency conversion fan automatically adjusts speed based on temperature, ensuring optimal heat dissipation, quieter operation, and reduced fuel use.
3. Low load design: Operates at no more than 90% power under full load, reducing wear, enhancing durability, and ensuring long-term stable performance.
4. Intelligent energy-saving control: Built-in stepless speed control system automatically adjusts engine speed to actual air demand, minimizing fuel consumption.
5. Durable box structure: Full galvanized plate enclosure offers excellent corrosion resistance and long-term reliability, even in harsh conditions.
6. High-efficiency compression host: Large rotor, low-speed two-stage screw design ensures lower specific power, higher energy utilization, stable operation, and extended service life—with a 5-year or 10,000-hour warranty.
7. Intelligent control system: Multifunctional controller for startup, shutdown, loading, and fault protection, plus global GPS and GPRS remote monitoring for remote operation and intelligent adjustment.

Working Principle

Utilizes advanced twin-screw compression technology. The core screw host features a pair of intermeshing Yin and Yang screws. Air is drawn in and compressed as the volume decreases in the chamber, raising pressure and producing stable, high-pressure air for all types of equipment.

1. Double-stage compression: Air is compressed twice, enhancing exhaust efficiency and reducing energy use for superior energy savings.
2. Intelligent adjustment: Automatic engine speed adaptation to gas demand keeps fuel consumption and exhaust volume perfectly matched, avoiding energy waste.
