What are the purchasing parameters of screw air compressor?

At present, there are many brands and models of air compressors above. If you want to choose a suitable Atlas air compressor, do you know the specific purchase parameters?
1. Exhaust pressure
In general, the greater the exhaust pressure of the air compressor, the more energy consumption. Generally, the diameter of the gas transmission pipeline of the air compressor can be larger to reduce the resistance loss and achieve the purpose of reducing energy consumption for long-term operation。
2. Exhaust volume of screw air compressor
If the exhaust volume is too low, it will not reach the specified value of the gas equipment; If the air compressor is too large, it will be uneconomical to operate due to high energy consumption, and the cost of purchasing screw air compressor with large exhaust volume will also be higher. Therefore, it is necessary to select an air compressor with appropriate air displacement。
3. Compressed air quality of air compressor: when selecting screw air compressor, appropriate supporting equipment shall also be considered to meet the requirements of air consumption equipment on compressed air quality。
If you want to reduce the oil content in the compressed gas, you can choose the oil purifier; If you want to reduce the water content in the compressed gas, you can use water removal equipment。
