Choosing an Air Compressor

In the past decade, the demand for energy-saving, reliable air compressors has increased. As an efficient source of compressed air, these air compressors have become the primary tool for industry and agriculture. The high-speed airflow in these compressors carries a large amount of lubricating oil through the sight glass. Consequently, poor oil separation effects lead to high oil content in the exhaust gas. To prevent such a situation, it is necessary to replace worn out and worn-out parts immediately.

Various air compressor types are used for different tasks. Vane compressors use a slotted rotor with variable-placed blades to guide air into a chamber and compress the volume. Vane compressors deliver fixed volumes of air at high pressure. Axial and centrifugal compressors are types of roto-dynamic compressors. In both types of compressors, the rotating vanes impart kinetic energy to the gas. A stationary passage converts this velocity to an increase in pressure.

When choosing an air compressor, make sure you check the discharge pressure before you start using it. The discharge pressure of a high-pressure compressor is usually less than two MPa. However, if you are using an air compressor for laser cutting, make sure that it can supply the necessary pressure. You may need more than one compressor for a particular task, so check the discharge pressure before buying. Besides, remember to check the discharge capacity of your air compressors. If you do not have the proper discharge capacity, you may end up with a bunch of rotten goods.

Apart from being an energy-efficient and reliable tool, air compressors have numerous applications. They are available for low, medium and high pressure requirements, depending on your requirements. It is also useful in other areas, like the construction industry, for instance, inflating tires and unclogging sinks. It is also used in refrigerators to chill air. The versatility of air compressors is staggering. It is a necessity for every industry and a must-have for any toolbox.

The basic units of an air compressor are single-stage or two-stage. The capacities of single-stage compressors are generally listed in horsepower (HP) or Standard Cubic Feet Per Minute (SCFM) or in pounds per square inch (PSI). The capacities of a two-stage compressor are sometimes listed in cubic feet per minute (CFM) whereas some are rated in actual cubic feet per minute. The former is more accurate, but the latter is inaccurate as it represents flow rate independent of the reference pressure.

In addition to oil-free air compressors, the oil-free versions are also available. In these industries, oil-free air is a critical requirement. An oil-free air compressor is a better option. A high-quality oil-free air compressor is ideal for the production line. Moreover, it is cost-efficient and environmentally-friendly. So, whether you need air compressors for your production line, or for industrial purposes, you will surely find a suitable model among these models.
