Air consumption in pneumatics

From FestoWiki - english
Jump to: navigation, search

The air required for pneumatics is of course not consumed, but the energy stored within it is typically converted from compressed air into movement. The air required for this purpose is called the air consumption, and this air consumption is required for planning and calculation of the costs.

Energy efficiency

Experience shows that compressed air costs are not only generated during operation but also, and to a considerable extent, during system downtimes.
Therefore, the golden rule "Ensure that compressed air is only consumed where work is actually performed" applies more than ever today.
