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
-
The WGD125 model air compressor is powered with one 23kW/30hp diesel engine which can produce compressed air of 85-125 cfm @ 7-10 bar pressure.
Both portable and skid version are available.What are the benefits of Diesel Air Compressor?
- ● Quiet design: Engine idles as low as 850 RPM to increase fueleconomy and reduce component wear; Noise level is 65 dBA at 20 feet when idling, whichis suitable for using in city construction; Operable at a Maximum ambient temperature overover 45 ‘C.
- ● Easier service and maintenance: Engine oil and coolant drain to the outside of thecompressor; Hand-operated compressor oil and fuel drains requireno tools; Canopy design is easy for maintenance.
- ● Durable , reliable construction: Engine is directly coupled to the airend by a rubbergear coupler for improved power transmission andreduce vibrations.
