towed rotary screw air compressor for highway construction

The towed rotary screw air compressor features a traction design for excellent maneuverability, enabling rapid transfers between construction sites and delivering efficient, continuous air supply. Advanced screw compression technology ensures high stability and low energy consumption, with reliable performance even in high temperature, low temperature, heavy dust, and high-altitude environments.

Working Principle of Towed Rotary Screw Air Compressor

• Two-stage screw compression: Utilizes a two-stage compression design to significantly improve efficiency and reduce energy consumption.
• Intelligent adjustment system: Equipped with a full-range stepless speed control system, it automatically adjusts engine speed based on real-time air usage to ensure optimal performance and minimal fuel consumption.
• Air is drawn through the inlet, compressed between the screw rotors (large rotor, low speed for stability), and discharged via the exhaust pipe to power tools and equipment.

Main Features

1. High efficiency and energy saving: Two-stage compression and stepless speed regulation auto-adjust to load changes, reducing energy waste and fuel consumption while maximizing efficiency.
2. Harsh environment adaptability: Operates stably in challenging conditions, including extreme temperatures, dust, and high altitude.
3. Low noise operation: Silicon oil frequency conversion fan adjusts speed with temperature, reducing noise and improving operational comfort.
4. Long-term reliability: Large rotor, low-speed screw design ensures durable, stable operation. Backed by a 5-year or 10,000-hour warranty, minimizing downtime and maintenance.
5. Enhanced air filtration: U.S. Frigidaire three-stage air filtration system offers large dust capacity and long-life filtration, protecting engine and screw host.
6. Optimized fuel system: Large-capacity fuel tank reduces refueling frequency; three-stage fuel filter protects the nozzle and pump, simplifying maintenance.
