This portable diesel air compressor is designed with a compact structure. A wide range of air compressors can meet your different demands in different fields. Small space usage, simplified installation, free online technical service, and less energy consumption. The CFAIR 390 CFM portable air compressor, with an efficient Cummins diesel engine, boasts a boost pressure of 10.5 bar. Its compact and portable design ensures versatility, making it ideal for various applications. The powerful Cummins engine and 10.5 bar pressure boost enhance its performance, catering to diverse compressed air needs in different settings.
CFAIR air compressor components generally have the following advantages:
Engine speed: Our engine is designed with a lower speed than other brands of engines. Lower speed means lower engine wear and longer service life. And lower speed can also achieve the same or even greater displacement as other brands. (Our team guarantees the authenticity of the data. If you have any questions, please contact the CFAIR team.)
GHH technology air compressor head: The GHH team has always played an important role in the field of compressor heads because of its reliable head quality and equipment processing based on German precision technology. It makes its compressor head durable, no matter what kind of harsh environment it is in. The CFAIR team uses the team's technology and precision machinery to make the head, which has a longer service life than traditional heads.
Double-layer nano-level air filter: Compared with the circular air filter of ordinary air compressors, the air filter designed by our CFAIR team uses nano-level filter materials and an integrated plain packaging method. This not only increases the filtration efficiency but also makes maintenance more convenient and reduces downtime.
Stainless steel parts: CFAIR air compressors use a large area of stainless steel spare parts with better quality and higher cost for considerations such as service life and corrosion resistance. Compared with ordinary air compressors, CFAIR air compressors have stronger resistance to harsh environments. This makes CFAIR air compressors have a longer service life.
Sound attenuation design: CFAIR air compressors have undergone rigorous sound attenuation treatment, such as flame-retardant sound insulation cotton, special pipeline silencing design, etc., which makes their noise level reach the industry's excellent level (78dB or less).

As one of the trusted diesel air compressor suppliers, we ensure each product combines durability, easy operation, and powerful output for demanding job sites. Our portable air compressors provide you with:
Famous Air End: At the heart of the compressors is an air end supported by German technology, continuing the tradition of reliable durability. The design method of our compressor head is processed using a high-precision CNC center. At the same time, we use an advanced three-dimensional coordinate system to conduct quality inspection on the product.
Long Runtimes: With improved fuel efficiency for up to 10 hours of runtime, there’s no need to stop midday to refuel.
Noise Reduction: Certain models may incorporate sound attenuation technology, such as QuieTech, to minimize noise levels during operation.
Easy Maneuverability: Our compressors feature a compact design for easier maneuverability, whether on the jobsite or behind a truck.
An Easy Controller: Our controller, which is on the curbside to help keep the operator safe, quickly and easily understands the status of the compressor, day in and day out.
High Power and Efficiency: These diesel engines are known for their high power output and efficiency, making them suitable for applications requiring continuous and heavy-duty operation.
Low Maintenance: Diesel engines often require less frequent maintenance compared to gasoline engines, reducing downtime and maintenance costs for the air compressor.
Versatility: Diesel-powered air compressors can operate in various environments and conditions, including remote locations or areas where electricity may not be readily available, providing versatility in usage.
Cold Weather Performance: Diesel engines perform well in cold weather conditions, making them suitable for operation in environments with low temperatures or during winter months.
Construction and Durability: The compressors are typically built with heavy-duty steel frames and powder-coated steel construction for durability and longevity. They may have corrosion-proof air intakes and watertight door seals to protect against harsh environments.
Easy Maintenance: Quick access air connections and large gullwing doors provide easy access for maintenance and servicing. Some models may have interior storage compartments for storing tools and accessories.
Air-Oil Separator Tank and Safety Valve: Registered pressure vessel design with manufacturer’s data report supplied. Non-adjustable, sealed, and stamped safety valve.
As a leading diesel-powered air compressor supplier, we understand the importance of reliability and efficiency on construction sites. Our industrial-grade air compressors are trusted by many professionals for heavy-duty construction work. We ensure that every unit is easy to operate and designed to deliver consistent power for a wide range of tools and on-site construction equipment. When you choose our company as your diesel-powered air compressor supplier, you’re investing in quality, performance, and long-term productivity.
Some of the most popular uses are as follows:
Drilling Machines and Jackhammers: These are often used to break up rocks and pavement and can be used in landscaping as well as construction. Aside from drilling, these tools can be used for countersinking, reaming, and tapping holes. They work best on flat, even ground without slopes, as they produce a quick chipping downwards motion.
Impact Wrenches: These are used where accurate torque is required, such as loosening or tightening nuts and bolts as well as fasteners. The most common use would be removing lug nuts from a car tire, but they are also often used in construction.
CFAIR390M-10.5 air compressor is generally used in the sandblasting and painting industry. Compared with the traditional 375 air compressor, the 390cfm air compressor has a higher exhaust volume of 15cfm and a larger exhaust redundancy. And the pressure of 10.5 bar is 0.5 bar higher than the traditional 10bar air compressor. It means that it has higher efficiency and better sandblasting effect in the sandblasting industry.
CF390 has multiple options. In sandblasting and painting applications, we usually recommend air compressors loaded with after-coolers, because air compressors equipped with after-coolers can produce drier and lower temperature compressed air, which is crucial for sandblasting, especially in the painting industry. Drier compressed air can greatly improve the quality of painting, and a lower temperature can also protect the compressor and back-end equipment. So usually its service life will be longer, whether it is a portable type or a box type air compressor.
