Why Use Compressed Air

Availability

The raw material for compressed air, i.e., atmospheric air, is freely available everywhere on the planet. Compressed air is versatile and adaptable; it easily flows through pipes and valves, quickly filling a space. It can be compressed to higher pressures, stored as energy, and used to perform many types of work processes. Compressed air is considered a power source like gas, electricity, and water, and is often referred to as the fourth utility.

Versatile Utility

Compressed air is versatile.

• Compressed air can be easily stored for its intended purpose, using storage tanks or bottles located in places where no other power is available or practical.
• Equipment operated by compressed air can function at extreme temperatures.
• Air tools are ideal for dirty applications, such as in steel mills and foundries, where destructive operating conditions would challenge the reliability of electric powered equipment.

Cost Effective

Compressed air can be managed to be cost-effective.

• Unlike the other utilities, compressed air is generated on-site, giving users much more control over its usage, quality, and generation cost.
• Compressed air usage can be easily monitored and controlled to deliver reliability, productivity, and efficiency.

Safety

Compressed air is safe.

• Compressed air is safe to discharge back into atmosphere. Leaks are not hazardous.
• Compressed air is safe to use in environments that are wet, explosive, or combustible where an electric device could present a safety concern.
• Compressed air can have a high degree of cleanliness, essential for applications where quality, hygiene and safety are imperative.
• Air tools are often much lighter and operate significantly cooler than their equivalently powered electrical counterparts, making air tools easier and safer to operate.

Compressed air is present across just about every industry and it is used for many functions; from running huge equipment to powering simple air tools. Compressed air is a valuable utility and is a safe power source when used properly. As with any other energy-carrying power source, compressed air should be regarded with caution and handled with care to avoid accidents and user injury.

The following standards and regulations should be consulted when using compressed air:

• ANSI/CAGI B19.1, Safety Standard for Air Compressor Systems
• CAGI B186.1, Safety Code for Portable Air Tools
• ISO 11148 Series
• OSHA regulations
