Pneumatics is the science that uses compressed air or pressurized air (or a similar gas, such as nitrogen) to transmit force and energy to certain pneumatic tools or devices used in various domestic and industrial applications.
Therefore, a pneumatic drill or a pneumatic hammer can destroy pavement with a metal chisel that is pumped up and down by compressed air and fed through an air hose.
Similarly, a spray gun uses compressed air to ensure a uniform result and the paint is applied under optimal conditions on the body of a car. In some cases and depending on applicability, the laws of pneumatics are similar to those of hydraulics.
Hydraulic vs. Pneumatic – Water vs. Gas
The difference lies in the fact that in the case of hydraulics, water (or another liquid) is used to transmit force and energy (as in the case of a bulldozer or crane).
Both are examples of power, only in the case of hydraulics tools, machinery or equipment use liquids, while in the case of pneumatic ones air or gas is used, especially nitrogen.
What are pneumatic tools?
Different pneumatic tools are mechanical instruments powered by compressed air. Some of the least known pneumatic tools are the drilling pump or pneumatic pump, and among the most common air-powered tools are pneumatic knives, capping devices or grinding machines, milling machines, saws and shears.
Current technology allows them to be manufactured in increasingly smaller and lighter sizes than in the case of electric tools, as they do not require the incorporation of an electric motor for power and operation.
