Masters, how to calculate the amount of compressed air to choose a large air compressor?

1 First of all, if you know the gas consumption and pressure of your equipment, it will be simple. For example, per minute 1. 1 m3, the pressure is 8Mpa, and a 7.5KW air compressor is selected. 1.6 cubic corresponds to 1 1KW, and so on. It should be noted that the displacement of the air compressor is better than the gas consumption of your equipment. When you don't know the gas consumption of your equipment, you can only contact the air compressor manufacturer, who can estimate the gas consumption according to the parameter power and other information of your equipment because of their supporting experience. For example, you are the air compressor of laser cutting machine. According to your experience, the 500W-4000W cutting machine recommends the air compressor of 1 1KW.
