Linsheng Electrical Company -Portable Air Compressor Terminology: 3 Things

Technical terms:

When deciding to buy a compressor, it is important to be familiar with all compressor technical terms. Although the number of compressor types is usually very large, it is easy to choose a suitable unit by asking some basic questions.

1. Performance level:

Matching one or more pneumatic tools to standard cubic feet per minute and PSI requirements is critical to the output capacity of the air compressor. Standard cubic feet per minute or SCFM is the rate of how much air the compressor can produce in one minute. All tools driven by a compressor are provided with SCFM values; this value will indicate the gas source necessary for optimal tool operation. Therefore, when matching the SCFM rating of your air compressor, check the standard cubic feet per minute at 90 psi.

Normal consumption of standard cubic feet per minute

Air filter: 3

Air hammer, light: 4

Heavy air hammer: 22

Air hoist, 1000 lbs: 5

Air motor -0.5 hp: 6-10

Air motor-1 hp: 12-15

Standard cubic feet per minute for pneumatic tools may vary. Some tools only require 1 or 2 SCFM, while other tools require 10-14 standard cubic feet per minute.

If you think it is possible to operate multiple tools at the same time, then obviously, you will really want more features. In this case, the minimum SCFM rate of the compressor is determined by adding together the cumulative SCFM specifications of the equipment to be operated simultaneously. In order to provide some buffer for the calculation, you need to increase the final figure by another 50%.

Pneumatic tool 1 = 2.0 SCFM + Pneumatic tool 2 = 1.0 SCFM Add them together, a total of 3.0 SCFM, plus 50% buffer, we have a total of 4.5 SCFM (standard cubic feet per minute), as a result you will try to find SCFM Compressors with ratings above 4.5 SCFM.

The minimum SCFM compressor rating can be determined by adding the SCFM ratings of any compressed air tools used simultaneously. If a pneumatic tool is to be operated separately, the SCFM of the highest rated pneumatic tool must be used.

2. Power:

Electric compressors are usually powered by a typical 110-120V power supply. However, air compressors with motor units greater than 2 HP may have to have a 220-240V power supply. If you plan to use an air compressor in a workshop, garage or any other confined space, you need an electric compressor.

Gas-operated air compressors do not depend on electrical energy, so they are truly mobile. However, pneumatic compressors have many disadvantages. The most important disadvantage is that gasoline-driven air compressors produce harmful gases, so they should not be operated indoors or even in any narrow working area. Another disadvantage of these compressors is that they require more repairs and maintenance than electric compressors.

3. The decibel level of a typical compressor:

When purchasing an air compressor, sound output is an important factor. The sound level of the air compressor is within the manufacturer ’s specifications. If you usually use the device in a house or small workshop, you may need to choose a quiet machine instead of using a deafening air compressor, so as not to damage your hearing. Therefore, you should find out the noise level before buying.
