How to choose screw air compressor and scroll air compressor

In the choice of screw air compressor and scroll air compressor, should consider the following aspects:

structural features and working principle:

the screw air compressor compresses air by changing the volume of the cogging of the male and female rotors in the casing. It has the characteristics of high operability, good power balance and strong adaptability.

The scroll air compressor uses two intermeshing spiral rotors (rotors) to rotate in the casing to compress air, with compact structure and stable operation.

Performance:

screw air compressors are favored for their simple structure, small size, no wearing parts, reliable work, long life, and simple maintenance. In particular, the water-lubricated screw air compressor produced by Shanghai Granklin Group also has the advantages of low noise and energy saving. It is suitable for the industrial field, especially the occasions that require highly clean oil-free air and large flow.

The structure of the scroll air compressor is relatively simple, small in size, light in weight, less wear, and high mechanical energy efficiency. It is suitable for environments that require low noise and low vibration, such as hospitals and laboratories. However, the precision requirements are high, and there are certain challenges in high-horsepower applications.

Maintenance and use costs:

the screw air compressor has few parts, no wearing parts, reliable operation, long life, tens of thousands of hours of overhaul interval, and convenient operation and maintenance.

The maintenance cost of the scroll air compressor is relatively low. Due to its simple structure, it is also easy to maintain and repair, and usually has a long service life.

Application Scenarios:

screw air compressor is widely used in a variety of industrial fields, especially in the need of high pressure, large flow of the occasion.

Scroll air compressors are suitable for places with high noise and vibration requirements, such as hospitals, pharmaceuticals, food and other industries, and are also favored for their environmental protection characteristics.

In summary, when choosing a screw air compressor and a scroll air compressor, it should be determined according to specific application requirements and scenarios. If you need high pressure, large flow of compressed air, and the noise and vibration requirements are not high, the screw air compressor is a better choice. If you need to use in a low-noise, low-vibration environment, or have higher requirements for air quality, the scroll air compressor is more appropriate.
