Introducing our high-end, precision-engineered CMW2.2-0.8 Oil-free Scroll Air Compressor, designed with a multitude of advantages for a superior performance and long-lasting durability.

Our compressor is designed with a high precision, high rigidity square structure ensuring an extremely long lifespan and a two-year mainframe warranty.
Equipped with a permanent magnet motor drive, the energy consumption is reduced by over 15%, significantly lowering your operational costs.
The motor is directly linked to the mainframe, eliminating the need for couplers or belts. This design not only minimizes maintenance but also reduces noise levels dramatically.
The compressor features a user-friendly LCD screen that displays real-time exhaust temperature, exhaust pressure, operating time, maintenance reminders, and fault alarms, ensuring a smooth and efficient operation.
The Single Mainframe model of our oil-free scroll air compressor is a masterpiece of engineering. It boasts numerous features:
The international first of its kind, this high rigidity mainframe is powered by a high-efficiency permanent magnet motor and equipped with a high-quality stainless steel air storage tank, independent cooling fan, efficient intake filter with a precision of 1 micron.
The precision mainframe, with its high precision, high rigidity four-square design, ensures easy operation at high pressure up to 1.2Mpa. It is durable and reliable.
The permanent magnet drive offers smooth startup, with no startup impact, and also features variable frequency speed regulation. This not only enhances durability and energy efficiency but also extends the lifespan of the compressor.
The independent cooling fan ensures that the compressed air is near ambient temperature, ensuring an extremely low moisture content.
The design is sleek and elegant, with an excellent structure. The advanced soundproof cover can reduce noise to as low as 49dB.

The Multi-Mainframe model of our oil-free scroll air compressor is flexible and adaptable. It boasts the following features:
This model is designed for flexibility and adaptability. It can cater to a wide range of usage scenarios, making it a versatile choice for different industries.
The modular design features 2 to 4 compression mainframes, fully considering various usage scenarios. The model optimizes operational efficiency, saving energy and electricity. It intelligently switches between main and auxiliary machines based on air usage, extending overall lifespan and maximizing energy efficiency.
The Equipment Compatible model of our oil-free scroll air compressor is extremely quiet and portable. It can be easily integrated into any equipment that requires compressed air. The unit does not require any lubricating oil, making it stable and reliable. Maintenance is minimal, with only an annual application of grease required. The only consumables are the air filter and sealing ring.

The oil-free scroll air compressor is composed of two overlapping scroll screws, one fixed and one rotating. The gap between the scroll screws forms a compression space.
As the rotating screw begins to rotate, air is drawn into the compression space through the compressor's intake port. During this process, the movement of the scroll screws draws in the air and gradually pushes it towards the center.
With the movement of the rotating screw, the air is pushed into a progressively smaller compression space, resulting in compressed air. This is achieved through the relative motion of the scroll screws and the reduction of the gap.
Once the air is compressed to the required pressure, it is discharged through the compressor's exhaust port. In this process, the movement of the scroll screws pushes the air towards the compressor's outlet.
The key feature of oil-free scroll air compressors is that they do not require lubricating oil to cool and lubricate the scroll screws. Instead, they use a special coating material, such as a polymer coating, to reduce friction between the scroll screws and ensure an efficient compression process.

We are proud to say that our full range of products have passed Germany's TUV class 0 oil-free certification, CE certification, ISO9001 certification, and TS16949 certification. We are the first domestic company to use water for internal cooling and lubrication in high-end screw compressors. We have also pioneered the launch of the second stage compression high pressure micro-oil screw compressor with a pressure reaching 4.0MPa worldwide. We then developed the world's first 4.0MPa pressure oil-free screw compressor and the world's first 1.25MPa pressure oil-free scroll compressor.
