Air compressor specific power: the smaller the better!

Let's first understand what "specific power" is.

You can think of the specific power "Gas Consumption".

For example, both cars can pull 1 ton of goods and run 100 kilometers. Car A burns 10 litres of oil and car B burns 7 litres of oil. The B car is more "fuel-efficient" and more efficient.

The same with the air compressor-- also produce a compressed air, who uses less electricity, whose specific power is smaller, who is more cost-effective.

So the conclusion is simple:

the smaller the power, the better, the smaller the power, the smaller the machine, the more "smart".

Why is power more important?

Because the air compressor is not bought back and finished, it is turn every day, turn every month, turn every year of.

Even if it is only a little bit worse than the power, the difference in electricity bills in a year may be frightening. Just like two refrigerators in the home, one consumes half a kilowatt-hour of electricity every day. You don't think it is much, but it is more than 180 kilowatt-hours of electricity in a year and more than 1,000 kilowatt-hours in ten years.

So when buying an air compressor, don't just look at the price, power is what really saves you money.

What are the advantages of water lubricated air compressors in this regard?

Traditional air compressors rely on oil for lubrication and sealing. The oil itself has resistance. The rotor turns like running in "mud" and consumes electricity. Moreover, the oil will thicken and age, and the resistance will be greater over time, and the specific power will slowly climb up.

And water-lubricated air compressor it's not the same:

• water has much less resistance than oil the rotor turns more smoothly inside, just like the difference between rowing in clear water and rowing in mud. Saving energy will naturally save electricity.
• Water does not age and thicken the lubrication effect is almost the same as long as it is used, so the specific power can always be kept at a relatively low level, and the more electricity it is used, the more electricity it will be used.
• In the process of compression, water can also take away heat directly. The machine is not easy to generate heat. If the heat is less, the efficiency will be high, and the specific power will naturally be low if the efficiency is high.

Simply put: water lubricated air compressor is inherently more "power saving physique" than oil lubricated, and it is easier to make smaller than power.

What do you think when choosing a machine?

You don't need to calculate those complicated numbers, just remember one principle:

for two machines with the same amount of gas, ask "whose power is lower than that" and choose the smaller one. In the long run, the electricity bill can save money for one machine.

Especially if you have requirements for air quality-such as food, medicine, electronics and other industries-you tend to choose models without oil and water lubrication or water lubrication, congratulations, saving electricity and clean air are two things that one machine can do at the same time.

One sentence summary

the specific power is the "power consumption report card" of the air compressor, the smaller the better. Because the water-lubricated air compressor has low water resistance, no aging, and good heat dissipation, it is naturally easy to get a smaller specific power, which saves electricity and produces clean gas. It is a "smart and clean" choice.
