China Air Compressor-Size, Power, CFM: Relationship With Air Compressor

Posted 2021-02-28 bertlinsheng

China Air Compressor   : The size, power and CFM of the air compressor is not difficult to understand, but it does require some research to fully grasp. Before making a purchase, it is best to determine your needs for these three aspects of the compressor. The first thing you need to figure out is how much air you will need and which tools will be used. These three factors are related to the air tank installed on the compressor unit, the power of the motor and the pressure released by the amount of air delivered.

Air compressor size
In terms of size, the compressor has many options. The largest tank size of course means that you will have more air. However, larger tanks are also more expensive and difficult to maintain. They will take up more space, if you want to put the air compressor in your home or garage, this will be a problem. You can get any tank from 1 gallon to 80 gallons, so you definitely want to consider the size of the tank that suits your needs.

To determine the best size, just figure out what you will do. If you want to power multiple pneumatic tools for a long time, you must purchase a larger fuel tank. When the air runs out, you will need to restore the used air, which will also take some time. Having a larger fuel tank, such as an 80-gallon air compressor, means that if you use some tools intermittently, you may never run out of air. However, for example, if you work with a gas tank, you need to have enough air to circulate continuously.

Again, consider what type of tool will be used. Nail guns and copper nail guns are powered by smaller air jets, instead of using so much air from the total tank distribution, so the compressor can quickly refuel it. Therefore, you can use pancakes or hot dog compressors to use these tools. Read more about the best air nails here, or read this sprayer guide in this article.

Compressor power
Power is another important consideration. Displayed in HP units (ie horsepower), the electric motor is the key factor in how much power the compressor can provide. For truly large compressors, horsepower ratings are 2-10 or even 15 HP. For air compressors used with standard power outlets, your power will be less than 2 horsepower. This is because the standard AC power cord only requires you to pass 15 amps of current-about 1800 watts. For every horsepower you have, your standard compressor will output about 4 CFM at 100 PSI.

Air Compressor CFM
Finally, when purchasing a new air compressor, consider CFM or cubic feet per minute. CFM essentially depends on how much air the device‘s pressure valve can exhaust. The actual rate of air expressed by CFM depends on the atmospheric pressure and humidity level. Therefore, you may also see CFM also displayed as SCFM, which means standard cubic feet per minute.

Find out your needs before choosing a unit
The CFM level is used together with the PSI value, so if the CFM increases, the PSI may decrease. To figure out how much size, power and CFM you need, ask yourself the following key questions. From hobbies to business purposes, what is the purpose of buying a compressor? How often do you use it throughout the day? What tools and equipment will it support? Do you need a fixed or portable device? Can it meet the needs of multiple users?

CFM requirements based on number of users and tool type

Each air compressor displays CFM requirements, and each compressor has a maximum CFM output. Its CFM output must exceed the requirements so that each tool can run efficiently without problems. Generally, for example, if you operate a pneumatic tool-based workshop, each worker needs about 5 CFM. A 1 / 2-inch impact wrench requires approximately 5 CFM at 90 PSI, so your compressor CFM should be larger.

Moreover, if you have 2 technicians operating these wrenches at the same time, you need a minimum of 10 CFM. These tools are used for about 20 to 30 seconds, and then stopped when they change the layer, while the mechanics in the body repair shop may need to use the grinder and grinder for 20 to 30 minutes each time they use it. At the level of continuous use, you need a higher CFM, which is why it is so important to first figure out how you will use the machine.
