Product Description
This diesel powered air compressor adopts an innovative four crank rocker transmission mechanism, which converts the circular motion of the crankshaft into a 90 degree reciprocating motion through a precisely designed transmission shaft, achieving stable and wave free power transmission. Its core feature lies in the periodic collaborative work of four cylinders - each cylinder independently completes the four stages of intake, compression, exhaust, and expansion, forming a continuous and efficient compressed air output.
The unique sealing system adopts a self-lubricating design with lubricating oil, forming a dynamic oil film seal between moving parts to ensure complete sealing inside the cylinder. This design not only achieves 100% oil-free purity of compressed air (compliant with ISO 8573-1 Class 0 standard), but also maintains pressure fluctuations of ≤ 0.1 bar during 2000 hours of continuous operation through precise control of lubricating oil volume and strengthened connecting rod structure.
The crankcase optimized for heavy-duty conditions is made of ductile iron cast as a whole, combined with a four crank phase difference layout, effectively balancing mechanical vibration, making this model particularly suitable for field operations such as mining drilling and bridge construction that require continuous high-pressure gas sources.

Our Advantage
Efficient and stable power output
Adopting a four crank rocker transmission mechanism, non fluctuating compression is achieved through 90 ° reciprocating motion, and the pressure output is stable within ± 0.1 bar, ensuring the reliability of continuous operation.
Pure oil-free compressed air
The original lubricating oil self-lubricating sealing system meets the ISO 8573-1 Class 0 oil-free standard, and the output air is completely oil-free, meeting the gas requirements of precision instruments.
Heavy duty durability design
Ductile iron crankcase and reinforced connecting rod structure, combined with 5.5L precise oil control, support 2000 hours of uninterrupted operation, suitable for harsh environments such as mining and bridge construction.
Intelligent Collaborative Work System
Four cylinder phase difference layout, intelligent coordination of intake/compression/exhaust processes, energy consumption reduced by 15% compared to traditional models, and production capacity increased by 20%.
Operation Guide
1.Preparation Phase
Place the device on a flat, well-ventilated site. Check that the diesel tank has sufficient fuel, and verify that all connections are tight and seals are leak-free.
2.Startup Procedure
Open the diesel valve, then pull the starter (or press the electric start button if equipped). Allow the device to idle for 1-2 minutes until stable, then adjust to the working speed.
3.Operation Monitoring
Monitor the pressure gauge in real time during operation to ensure the working pressure remains within 2 bar. If abnormal pressure fluctuations or unusual noises occur, stop the machine immediately for inspection.
4.Shutdown Steps
Reduce the speed to idle, run for 30 seconds, then close the diesel valve. Once the device has completely stopped, clean dust and debris from the surface to maintain daily upkeep.
Customer Reviews
Feedback from Middle East Oil Service Company
"In the UAE desert oil field project, our diesel air compressor has been running continuously for 18 months without any seal failure, and the output pressure has remained stable at 8 ± 0.1 bar. I am particularly satisfied with its oil-free characteristics, which have extended the replacement cycle of the drilling equipment filter by three times. Suggest adding a heat dissipation warning function in high-temperature environments."
Evaluation of South American Mining Group
"The 20 equipment used in the Chilean copper mine still achieved 95% of its nominal capacity at an altitude of 4000 meters. The self-lubricating system effectively solved the wear problem in high dust environments, but it is recommended to optimize the starting program of high-altitude engines."

FAQ
1.Q: What is the recommended continuous working time for the device?
A: We recommend no more than 4 hours of continuous operation at a time. After that, shut down the machine to cool for 15-20 minutes to avoid overheating and extend the device’s lifespan.
2.Q: Does the oil-free device require regular maintenance?
A: Yes. We advise checking and cleaning the air intake filter monthly (replace if heavily clogged), and inspecting the body seals quarterly to prevent air leaks that reduce efficiency.
3.Q: Can the working pressure be adjusted manually?
A: The working pressure of this model is preset to 2 bar and cannot be adjusted independently. For higher pressure requirements, please select a model with the corresponding pressure rating.
