40 APRIL 2024 WorldWide Drilling Resource® Fun Facts About Compressed Air Adapted from Information by VMAC There are many questions when it comes to compressed air. In this article, we hope to answer many of those questions. Earth’s atmosphere is composed of about 78% nitrogen, 21% oxygen, and one percent of other gases. Compressed air is the same air as earth’s atmosphere, but has been forced into a smaller volume, with pressure greater than atmospheric. Air is compressed into a container and it becomes pressurized, it is then forced through an opening in the container, where pressure builds up. Have you ever wondered what the inside of an air compressor, while working, looks like? Imagine yourself in a packed elevator, the air molecules in a compressor, are trapped in a small space, waiting to be let out. Once those elevator doors open, everyone rushes out, that’s the same thing air does when given the chance. This is what causes the pressure in a compressor. There are three laws which explain air pressure. Boyle’s Law explains if air volume halves during compression, the pressure is doubled. Charles’ Law states, the volume of air changes in direct proportion to the temperature. The First Law of Thermodynamics tells us an increase in pressure equals a rise in heat, and compressing air creates a proportional increase in heat. These laws are explaining that pressure, volume, and temperature are proportional. This is how you can control the air volume and pressure while using an air compressor. Compressed air is useful as an energy source and for blowing air, known as active air. As an energy source, power tools and production equipment are powered by compressed air. Active air is used when a steady stream of air is needed for a task. Aeration and medical breathing air, are considered active air. Fun fact, some roller coasters use compressed air. If you think about it, many of the products we use everyday are made using compressed air. There are many different types of air compressors, like the rotary screw, and hydraulic air compressor. When looking for an air compressor, make sure to research for one that fits your needs. When it comes to safety, compressed air is clean, simple, and efficient. When used in unconventional ways it can be dangerous and even deadly. Always follow the guidelines to stay safe when using compressed air.
