The sandblasting process is widely used. Almost every kind of utensils in our life need sandblasting in the process of strengthening or beautifying in the production process: stainless steel faucets, lampshades, kitchen utensils, car axles, airplanes and so on. The sandb...Read more -
When should an air compressor be replaced?
If your compressor is in deteriorating condition and is facing retirement, or if it no longer meets your requirements, it may be time to find out what compressors are available and how to replace your old compressor with a new one. Purchasing a new air compressor is not as easy as buying new hou...Read more -
Homogenized compressed air system equipment industry
The sales status of the compressed air system equipment industry is fierce competition. It is mainly manifested in four homogenizations: homogeneous market, homogeneous products, homogeneous production, and homogeneous sales. First of all, let's look at the homogeneous m...Read more -
Air compressors have roughly gone through three stages of development in my country
The first stage is the era of piston compressors. Before 1999, the main compressor products in my country's market were piston compressors, and downstream enterprises had insufficient understanding of screw compressors, and the demand was not large. At this stage, foreig...Read more -
Single-Stage Compressor vs Two-Stage Compressor
Let OPPAIR show you how a single-stage compressor works. In fact, the main difference between a single-stage compressor and a two-stage compressor is the difference in their performance. So, if you are wondering what is the difference between these two compressors, then let’s take a look at how i...Read more -
Do you know why the screw air compressor has insufficient displacement and low pressure? OPPAIR will tell you below
There are four common reasons for insufficient displacement and low pressure of screw air compressors: 1. There is no contact between the yin and yang rotors of the screw and between the rotor and the casing during operation, and a certain gap is maintained, so gas leaka...Read more -
