良いエアコンプレッサーは何CFM？

CFM (cubic feet per minute) is a key indicator for measuring the flow rate of エアーコンプレッサーs. So, what CFM value makes an air compressor good? This article will explore the CFM of air compressors and provide answers using oil free air compressors and diesel screw air compressors as examples.

Understanding CFM and Its Importance

CFM is the principal figure that will give you a clear vision of whether a specific air compressor will be the best fit to supply air in various tools and applications. It represents the amount of air that an air compressor can generate per minute at a given pressure. Be it air-driven tools, paint sprayers, or even pneumatic machinery, the knowledge of the CFM needed will greatly improve the performance of the tool.

Low CFM Needs: A compressor rated with a CFM of 2 to 4 is usually an adequate match for minor tasks like inflating tires and small air tools. Apart from being portable, these compressors are also the easiest to use.

Medium CFM Needs: Compressors that discharge a CFM of 5 to 10 when carrying out operations like nail guns, impact wrenches, and paint spraying are certainly more powerful and cut the labor involved. Were you to choose within this continuum, there would be adequate air movement to keep the operation going without pause.

High CFM Needs: Heavy tools like sanders, grinders or those that need to be functional are appropriate examples that demand more than 10 CFM. This is particularly true when in an industrial setting, where a higher capacity diesel screw air compressor not only does it have more than 10 CFM but also it is very stable throughout the operation and safe, with several tools working at the same time.

While you’re contemplating which air compressor to choose, consider the following things together with CFM:

1. Type of Air Compressor

Oil Free Air Compressors: These compressors are absolutely great for applications where non-polluting air is needed. Along with their quiet mode of work, they are suitable for activities such as spray painting and medical applications.

ディーゼルスクリューエアコンプレッサーs: These compressors are designed to be used non-stop in heavy-duty industries, so they provide high CFM ratings that are great for industrial applications. They can be moved from one place to another, which means they can work outdoors in remote areas where there is no electricity.

2. Pressure Requirements

CFM is closely connected with PSI (pressure at which the air is supplied), which is often specified by the tool manufacturers. Ensure that the CFM value of your choice is inline with the PSI demands of your tools. If your tool needs 90 PSI, then the compressor has to provide the amount of CFM given at that pressure.

3. Tank Size

The tank size of an air compressor is also a critical factor that directly influences performance. A larger air tank helps spread the start-up air consumption of machines that temporarily require high CFM flow. For industrial applications, a minimum of 20 gallons is recommended for continuous operating time.

Benefits of Choosing the Right CFM

Efficiency: Choosing an air compressor that matches the CFM level required by your tools will keep them working without interruption.

Cost-Effectiveness: Compressors with matching CFM levels will save you money over time. You do not have to make additional purchases of compressors and tools for the reason of insufficient airflow

Longevity: The right air compressor is used to decrease the possibility of wear and tear on your tools. Monitoring air distribution at optimal pressure levels prevents cracks in your equipment.

結論

In summary, understanding CFM is essential when selecting an air compressor. A good air compressor should match the CFM requirements of your tools and applications. Whatever air compressor you choose, make sure you choose a model with the right CFM rating.
