◆ Type selection of working pressure (exhaust pressure)
When the user is ready to purchase an air compressor, the first thing is to determine the working pressure needed at the gas end, plus a margin of 1-2 bars, and then select the pressure of the air compressor. (This margin is to consider the pressure loss from the installation site of the air compressor to the actual pipeline of the gas end, and to consider the pressure margin between 1-2 bars according to the length of the distance). Of course, the size of pipeline diameter and the number of turning points are also factors affecting pressure loss, the larger the pipeline diameter and the fewer turning points, the smaller the pressure loss; conversely, the greater the pressure loss.
Therefore, when the distance between the air compressor and the gas-end pipeline is too far, the diameter of the main pipeline should be enlarged appropriately. If the environmental conditions meet the installation requirements of the air compressor and the working conditions permit, it can be installed near the gas terminal.

◆ Selection of volume flow rate
① When choosing the volume flow rate of air compressor, we should first know the volume flow rate of all the gas-using equipment and multiply the total flow rate by 1.2 (that is, to enlarge the 20% margin).
② the new project can be selected according to the flow rate provided by the design institute.
③ to understand the volume and flow parameters of the gas consumption equipment for the gas supplier.

④ Air compressor station transformation can refer to the original parameter value and the actual gas consumption.
Appropriate type selection is beneficial to users and air compressor equipment. Too much waste of type selection and too small type selection may cause the air compressor to be in a long-term loading state or insufficient gas consumption or pressure can’t be beaten up.

◆ Consider the quality of compressed air.

Generally, compressed air produced by air compressors contains a certain amount of lubricating oil and a certain amount of water. In some cases, oil and water are forbidden. At this time, attention should be paid not only to the selection of air compressors, but also to the addition of ancillary devices when necessary.
The solution is to select a non-lubricated air compressor. The air compressor cylinder is basically oil-free, and its piston rings and fillers are generally polytetrafluoroethylene. But this machine also has shortcomings, poor lubrication, high failure rate; PTFE is also a harmful substance, food, pharmaceutical industry can’t use; no lubrication air compressor can only achieve gas transmission without oil, can’t do without water. The second and commonly used method is to add the air compressor (either) to the first or second stage purification device or dryer. This device can make the air of air compressor contain neither oil nor water, and make the oil and water content in compressed air less than 5 ppm, which can meet the technological requirements.

◆ We should consider the safety of air compressor operation.
Air compressor is a kind of machine working under pressure, which is accompanied by temperature rise and pressure, and its safety should be put in the first place. The state implements a standardized "two certificates" system for the production of air compressors, i.e. air compressor production license and pressure vessel production license (gas storage tank). Therefore, when selecting air compressor products, we must strictly examine the "two certificates". Usually the quality assurance system of certified manufacturer is perfect, there will be no major quality problems, even if there are some problems, the manufacturer will be responsible for three packages.
