What is compressed air and how does it work?
People frequently ask: What is compressed air? Simply put, compressed air is air that has been pressurized using a compressor. This compressed air plays an important role in various applications, from industrial processes to medical equipment. In this blog, we explain not only what compressed air is, but also why it is so important and how it is used in various industries….
Compressed air is actually nothing more than atmospheric air compressed to a smaller volume. When air is compressed, the molecules move faster, leading to an increase in kinetic energy. This energy can then be stored and used when needed, making compressed air a very flexible and efficient energy source.
The air around us consists mainly of oxygen and nitrogen, with small amounts of other gases. When this air is drawn in by a compressor and compressed, it creates compressed air that is under high pressure. This process allows the air to be used for a wide range of applications.
What is compressed air used for?
We see compressed air being used in a variety of industries. It is an indispensable resource in industrial processes, where it is used to drive machinery, move products and even to run tools.
Here are some other examples:
- Pneumatic tools: These tools, powered by compressed air, are widely used in construction, automotive and maintenance work. They are popular because of their reliability and the fact that they are relatively safe to use, especially in environments with wet floors or high humidity.
- Medicinal air: In the medical sector, compressed air is used in respirators and other life-saving applications. Medicinal air must meet strict quality standards since patients’ health depends on it.
- Packing and conveying: In many different industries, such as the food industry, compressed air helps pack and transport products without the risk of contamination.
- Simple logical circuits: Compressed air is also used in control systems, where it helps execute simple logic circuits that control machines and devices.
- Nitrogen generator: Nitrogen generators can generate nitrogen through compressed air.
Different compressors and compression techniques
A variety of compressors and compression technologies are available. Compressors can range from small, portable units to large, industrial systems. Choosing the right compressor is crucial for process efficiency and reliability. We therefore work with compressors from well-known brands such as: Mattei, Airpress, ALUP and Kaeser.
The most common different compression techniques are:
- Piston compressors: These work by compressing air in a cylinder using a piston. They are simple in design and maintenance, but can be noisy.
- Screw compressors: These use two screws to compress air. They are more efficient and quieter than piston compressors and are often used in continuous production processes.
The energy consumption of compressed air compressors
An important aspect of compressed air is energy consumption. Although compressed air is versatile and useful, it can be energy intensive to produce. Compressors are known to be responsible for a significant portion of energy consumption in industrial environments. Therefore, it is essential to keep energy efficiency in mind when designing and operating compressed air systems.
We advise our customers to invest in modern, energy-efficient compressors and to perform regular maintenance to minimize energy consumption. This helps reduce operating costs. View our compressor control system here.
The quality of compressed air
Compressed air quality is very important, especially in applications where contaminants are a major risk, such as in the food and medical industries. Compressed air can contain moisture, oil and other particles that can be harmful to equipment and processes. Therefore, it is important to purify and dry the air before it is used. We offer several solutions to ensure that your compressed air system meets the highest quality standards.
Why use compressed air?
With so many options available, why should companies use compressed air? One of the main reasons is the relative safety of compressed air compared to other energy sources such as electricity. In environments with explosion hazards or high humidity, compressed air offers a safe and reliable solution.
Compressed air is also commonly used for inflating tires, powering machinery, and creating motion in industrial processes. The versatility and reliability of compressed air make it an indispensable resource in numerous industries.
