• Low noise levels protect ambient conditions and workers’ hearing.
• Almost 100% recyclable at end of service life to save the earth’s precious resources.
Diesel engine features:
1）The choice of engine for each compressor model is made to ensure optimal performance and reliability while minimizing fuel consumption.
2） It boasts industry-leading levels of low fuel consumption, exhaust emissions, and noise. An automatic fuel priming and air bleed system negates the necessity of opening injector lines in the event of fuel depletion.
3）Additionally, it incorporates a two-stage fuel filtration system comprising a water sedimenter and a high-capacity pleated filter element.
A diesel engine driven air compressor is used to supply compressed air in locations where electricity is not available or not reliable. It is commonly used in construction sites, mining operations, offshore platforms, and oil fields to power pneumatic tools, equipment cleaning, drilling support, and maintenance tasks.
A 900 CFM air compressor provides a high volume of continuous air output, making it suitable for heavy-duty industrial applications. It can support multiple pneumatic tools at the same time and is ideal for large-scale operations such as offshore drilling, oil field maintenance, and mining projects where stable air supply is critical.
An oil-free air compressor works by compressing air without introducing any lubricating oil into the compression chamber. It uses special coatings, seals, or dry-running components to keep the air path completely oil-free.
Air is drawn in, compressed by pistons or screws, and delivered as clean air, while lubrication for moving parts is isolated from the air system. This ensures the output air remains free from contamination.
It is widely used in offshore, oil & gas, and industrial applications where clean and reliable air supply is required.
An oil-free air diesel compressor produces clean compressed air without oil contamination, making it suitable for sensitive applications such as oil & gas operations, chemical processing, and environments where air purity is important. Oil-lubricated compressors are generally more cost-effective but may introduce oil particles into the air stream.
To choose the right diesel air compressor, you should consider airflow (CFM), working pressure (bar/psi), application type, and working environment. For offshore oil fields and heavy industrial use, high-capacity models like 900 CFM units are recommended to ensure stable and efficient air supply.
