High-pressure drilling rig air compressors are equipment specifically designed for heavy-duty working conditions such as mining drilling and blasting, and rock drilling. Their core parameters are air pressure (typically ≥1.4MPa) and displacement. They must be used in conjunction with down-the-hole drills or rock drills.
High-pressure air compressors are mainly used in oil and gas extraction, mining drilling and blasting, pipeline construction, and in the steel, power, and metallurgical industries.
- Equipped with a high-power engine and heavy-duty system design, it boasts excellent starting performance and outstanding fuel economy, adapting to various harsh operating conditions.
- Two-stage compression ensures higher compression efficiency and provides more ample pressure. The compressor head utilizes a new high-efficiency profile, maximizing compression efficiency, reducing compressed air leakage, and guaranteeing sufficient pressure and discharge volume.
Smart Controller
- A uniquely developed control system with multi-threaded engine control allows for real-time dynamic adjustment of air volume and pressure to suit appropriate conditions, reducing excessive energy consumption.
- ● Ensuring Low Pressure Drop
- ● Efficient separation, low oil content ( less than 3ppm ).

Product Name: Diesel Air Compressor / Portable Diesel Air Compressor / Mobile Diesel Screw Compressor
Product Description:
The Diesel Air Compressor is a powerful, self-contained mobile air supply system designed for heavy-duty construction, mining, infrastructure development, and industrial maintenance applications where reliable compressed air is needed in remote locations without access to electrical grids. Powered by rugged diesel engines and typically featuring oil-injected rotary screw technology, these portable units deliver consistent, high-volume airflow – from 40 CFM for light pneumatic tools up to 1250 CFM or more for large-scale drilling and sandblasting operations.
Unlike stationary electric compressors that require permanent installation and grid power, diesel air compressors are built for mobility and autonomy. Mounted on rugged chassis with towing hitches, skids, or truck beds, they can be transported to any jobsite and operated continuously for full shifts – often running 8+ hours on a single fuel tank. They are the industry standard for outdoor pneumatic power wherever electricity is unavailable or impractical.
Key Features & Benefits:
-
Diesel Engine Powered – High-torque liquid-cooled diesel engines from trusted manufacturers such as Kubota, John Deere, Cummins, Hino, Perkins, and Ashok Leyland provide reliable, fuel-efficient operation in demanding environments .
-
Rotary Screw Technology – Most mobile diesel compressors utilize oil-injected rotary screw air ends for continuous, pulsation-free airflow. This technology supports 100% duty cycle operation – meaning the compressor can run at full load continuously without overheating or damage
- Customization Options: As a leading Construction Machinery & Warehouse Equipment Supplier, we offer OEM services
