The Cost of Compressed Air
A question that is occasionally asked by our customers to Ash Air is 'what is the cost of compressed air?' This article looks at the product costs involved with compressed air, as well as minimising the energy cost of compressors and cost allocation. When looking at these factors, we need to realise what causes dropped efficiency of your compressor, leading to increased costs of compressed air.
- Air Leaks - are a common cause of wasted compressed air, infact 10%-30% is wasted through leaks.
- Pressure Drop -filters, air dryers, valves, and piping are all in-out systems which cause and create pressure drops. To compensate for pressure drops, you'll find that the compressor will have to be set to a higher pressure than usual, which in turn increases the energy cost.
- Pressure to high (Artificial Demand) - this is seen when you use a pressure that is higher that what you really need. If your compressor operates at 8 bar, but only really needs 7, then you'll find that the extra 1 bar isn't actually needed, and if your compressor has leaks at the higher pressure level you will unfortunately end up losing more energy.
- Inefficient air production - assumptions are commonly made that the compressor runs at full load when operating, when really the compressor will sometimes start and stop, running unloaded and fluctuations of pressure and air demand will be evident.
Another point to make is about the power of knowledge - having knowledge of your compressor, its specifications and its suitable operating capabilities will definitely help you on your journey to understanding and recognising when your compressor is functioning well, and when it isn't. Caring for your compressor system, regular servicing and check ups will help you greatly to reduce wasted cost every day of the year. A compressor system that is say, medium sized can amazingly save between $10,000 and $30,000 per year!

The production costs of compressed air
The production costs of compressed air can vary. When planning a new investment, it is best to look as far into the future as possible and attempt to assess the impacts of new situations and demands that might affect the compressed air installation. Typical examples include environmental demands, energy-saving demands, increased quality requirements from production and future production expansion investments.
