Compressed air is air that has been “compressed” so that its pressure is greater than standard atmospheric pressure (14 psi). The expansion of the pressurized air provides a safe, effective medium for transmitting energy. Compressed air can be easily stored in a tank, cylinder, or other container until needed.
Air compressors are machines used to create compressed air. They do so through two types of air displacement: positive displacement (increasing pressure by forcing the air into a confined space) or dynamic displacement (pressure is created by accelerating the air to a high velocity). Which approach is used for a particular application depends on factors such as required pressure, flow rate, and application.
The Different Types of Air Compressors
While there are different methods for compressing air, the basic process is the same. The compressor draws in ambient air from the surrounding environment through an intake valve and compresses it to a desired pressure. There are several different kinds of air compressors:
- Reciprocating compressors use pistons to compress the air inside a cylinder.
- Rotary screw compressors use two rotating helical screws (male and female) to compress air.
- Rotary valve compressors use a rotor with vanes that slide in and out of slots to compress air.
- Centrifugal compressors use a high-speed impeller to accelerate air and then a diffuser to convert kinetic energy into pressure. Centrifugal compressors are used in large-scale industrial applications.
- Scroll compressors use two spiral-shaped scrolls—one fixed and one orbiting—to compress air. This method is commonly used for smaller air compressors and HVAC systems.
Advantages of Using Compressed Air
There are many reasons why compressed air is such a popular energy option. Some of the benefits provided by air compressors and compressed air include:
- Safer than other forms of energy
- Provides a steady, reliable source of energy
- Easy to use and store
- Energy efficient
- Compressors can be compact and used on-site
Applications for Compressed Air
Another benefit is versatility. Air compressors and compressed air are used in a wide range of applications, including pneumatic tools, air brakes, spray painting, SCUBA diving, air blowers, air guns, respirators, and more.
The performance of an air compressor and compressed air power system depends a great deal on the hoses and connectors used to transport the compressed air. Manufacturing flaws and inferior construction materials in these components can impact the efficient performance of a pneumatic system. Even tiny defects can greatly reduce pressure and flow.
