Key Specifications

Key Applications

• Pneumatic tools (jackhammers, rivet guns)
• Mining & quarry drilling
• Sandblasting & surface preparation
• Road construction & maintenance
• Pipeline pressure testing

Core Features

1. High-Efficiency Screw Air End
Precision-engineered rotary twin-screw element with durable bearings ensures stable airflow at 8 bar, minimizing pressure drop and maximizing efficiency. Oil-injected lubrication system reduces wear and extends service life.

2. Reliable Diesel Engine Power
Powered by a water-cooled, turbocharged diesel engine meeting emission standards. The direct-drive configuration eliminates belt losses, ensuring optimal power transfer and lower fuel consumption. Average fuel consumption: 10–12 L/hour.

3. Portable & Rugged Design
Heavy-duty chassis with optional wheel/trailer mounting enables easy site-to-site transport. Weatherproof canopy protects components from dust and moisture, suitable for harsh outdoor environments.

4. Intelligent Control System

Micro PLC controller monitors key operating parameters including discharge pressure, exhaust temperature, engine oil pressure, water temperature, and fuel level. Automatic alarm and shutdown protection ensure safe operation.

5. Low Maintenance & Service-Friendly

Single-side access to service points, easily removable panels, and strategically placed components reduce downtime. High-capacity air and oil filtration systems extend maintenance intervals.
