Compared with other volumetric compressors, oil-free silent air compressors have many irreplaceable advantages. Firstly, it has a simple structure, small size, and light weight. The number of main components is only 1/10 of that of a reciprocating compressor, with a volume reduction of about 40% and a weight reduction of over 15%. The suction, compression, and exhaust processes of a vortex compressor are carried out together and continuously, and the suction and exhaust chambers are not directly adjacent, resulting in smaller leakage and higher power.

The working chamber of the tightening machine is not connected to the suction and exhaust ports together, and there is no need to set suction and exhaust valves. This reduces the loss of intake and exhaust on the one hand, avoids the knocking noise and oscillation caused by the air valve on the other hand, and also reduces a group of vulnerable parts, improving the reliability of the tightening machine.

The suction duration of a vortex compressor is much better than that of other types of compressors, and its intake process is active and inclusive. This is different from the forced suction of other types of compressors, and even the suction boost effect may occur, so the volumetric power is particularly high. Working together with multiple working chambers results in a very small driving torque of the compressor, which is only 10% of that of the rolling piston compressor and reciprocating compressor. All of these characteristics make the vortex compressor have excellent thermal and frequency conversion characteristics, making it highly successful and widely used in the commercial field.

The vortex compressor, as a power air compressor, gradually developed at the end of the 20th century. There are many types and standards of air compressors, and small air compressors with an exhaust capacity between 0.1m3/min and 3m3/min account for a large proportion of air compressors. The demand for them in shopping malls is also very high, and now the main ones occupying this part of the market are reciprocating and screw compressors.

Although the reciprocating compressor has a low price, it has high oscillation noise, many vulnerable parts, poor reliability, and high maintenance costs; The screw type tightening machine has good reliability, but its profile is a three-dimensional change curve, and the volume power of the screw type is low within a small exhaust range, which requires high machining accuracy for the profile, resulting in high machining costs; The vortex compressor has the advantages of both reciprocating and screw compressors: the processing is much simpler than the screw compressor, and the reliability is higher, there are no vulnerable parts, and the operation and maintenance cost is low. It can fully leverage the benefits of the vortex compressor and is expected to gradually replace the reciprocating and screw compressors in the range of 1.5HP to 30HP to become a mainstream model, becoming a new expectation for micro and small air compressors.
