What is the ratio of general air compressor gas production and power?

General air compressor gas production and power ratio, in the most popular words is: every 1 kW of power, about every minute can produce 0.15 to 0.18 cubic meters of compressed air. On the other hand, if you want the machine to spit out 1 cubic meter of gas per minute, you need to consume about 5.5 to 7 kW of electricity.

Give some practical examples to help you understand. A 3.7 kW machine, about 0.63 cubic meters of gas per minute. A 7.5 kW machine produces about 1.38 cubic meters of gas per minute. A 37 kW machine, about 6 cubic meters of gas per minute. You will find that basically every 6 kW of power corresponds to 1 cubic meters of gas per minute, which is relatively close to most screw machines.

This ratio is actually the "specific power" in the industry. The lower the value, the more energy the machine saves, and the same one-time power produces more gas.

Water-lubricated air compressors have a small advantage in this matter. Because it uses water instead of oil for lubrication and sealing, the friction resistance inside the machine is smaller than that of the traditional oil-lubricated machine, so under the same power, the gas production of the water-lubricated air compressor will be slightly higher, or it will need slightly less power to achieve the same gas volume. At the same time, because there is no resistance loss of oil, the gas output is more stable, and the gas volume will not be large or small due to changes in oil temperature.

In general, just remember an approximate number: 1 kW power is about 0.16 cubic meters of gas per minute, or vice versa, 1 cubic meter of gas per minute requires about 6 kW power. Water lubricated air compressor can save a little on this basis.

If you want to know whether the specific power of your existing equipment is power saving, you can continue to talk.
