For example: A manufacturer operates a 200 hp compressor, 24 hours a day, 365 days a year. Many manufacturers overlooked compressed air costs for years when power was inexpensive, but as energy costs have increased significantly, it is imperative that facilities become educated about how important the total cost of ownership of their compressed air system is to saving money. The bottom line is, maximizing energy efficiency saves money. This fact makes it a wise decision to purchase the most energy efficient equipment available and to operate it in a manner so it delivers its maximum efficiency.
Over the lifespan of a typical compressor, energy typically costs several times more than the purchase price of the compressor. The most expensive component in the total cost of ownership of a compressed air system is the energy required to produce and deliver an uninterrupted supply of clean, dry compressed air at a stable pressure to every application in the system. The efficiency focus of compressed air becomes that of producing it as inexpensively as possible and not wasting it. Despite this inefficient conversion of energy, compressed air usage surpasses both electric and hydraulic power sources for industry, largely based upon the prominent benefits of using compressed air. It takes approximately 8 horsepower worth of electrical energy to produce 1 horsepower worth of compressed air energy.

CAGI B186.1, Safety Code for Portable Air ToolsĪlthough air is free, the cost to compress, treat, and distribute compressed air is significant.ANSI/CAGI B19.1, Safety Standard for Air Compressor Systems.The following standards and regulations should be consulted when using compressed air: 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. Compressed air is a valuable utility and is a safe power source when used properly. Air tools are often much lighter and operate significantly cooler than their equivalently powered electrical counterparts, making air tools easier and safer to operate.Ĭompressed 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 can have a high degree of cleanliness, essential for applications where quality, hygiene and safety are imperative.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 is safe to discharge back into atmosphere.Compressed air usage can be easily monitored and controlled to deliver reliability, productivity, and efficiency.Unlike the other utilities, compressed air is generated on-site, giving users much more control over its usage, quality, and generation cost.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.Ĭompressed air can be managed to be cost-effective.Equipment operated by compressed air can function at extreme temperatures.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.Compressed air is considered a power source like gas, electricity, and water, and is often referred to as the fourth utility. It can be compressed to higher pressures, stored as energy, and used to perform many types of work processes. Compressed air is versatile and adaptable it easily flows through pipes and valves, quickly filling a space. Depending on the room, we might need to perform multiple air changes per hour to achieve our desired air quality in that room.The raw material for compressed air, i.e., atmospheric air, is freely available everywhere on the planet. In order to remove these air pollutants, we have to change the air in the room by introducing new volumes of air. Having adequate ventilation and airflow in a room is essential for breathing and for some appliances and equipment to work properly.Īside from that, with correct ventilation, we can control the humidity and temperature in a room and quickly remove any odors, fumes, and even particles that might linger, like in the kitchen or living room. Each room has a specific purpose, and we stay in each room for different amounts of time during the day.ĭepending on the activities we do in a room, the ventilation required to maintain a fresh air flow will change. In most workplaces, we usually have a lobby or receiving area, hallways, function rooms, offices, restrooms, and so much more. We commonly find a living room, bedroom, dining area, kitchen, and bathroom in a basic house. In any building, there will be a variety of rooms with various functions and purposes.
