A pneumatic tool or air tool or air powered tool or pneumatic powered tool is one type of power tools, driven by compressed air, supplied by an air compressor, one type of gas compressors. Pneumatic tools can also be driven by compressed carbon dioxide (CO

) stored in small cylinders allowing for portability. Pneumatic tools are safer to run and maintain than their electric power tool counterparts, as well as having a higher power-to-weight ratio, allowing a smaller, lighter tool to accomplish the same task. General grade pneumatic tools with short life span are commonly cheaper and are also called disposable tools in tooling industries while industrial grade pneumatic tools with long life span are more expensive. In general, pneumatic tools are cheaper than its equivalent electric powered tools.

Air tools were formerly unpopular in the DIY market, but are becoming increasingly popular, and have always been ubiquitous in industrial and manufacturing settings.

Technical Terms[edit]

It is important to know some general specification technical terms used in pneumatic tools while it is also related to how to choose a good air compressor and if the tool can meet your job requirement so that an air tool can be used properly, respectively, Free Speed (rpm),Air Pressure(psi/bar), Air Consumption(cfm/scfm or m3/min), Horse Power(hp), spindle size...etc. Depending on different type of pneumatic tools, there are different specification values that you need to pay attention to.

Flow or airflow, related to air consumption in pneumatic tools, represents the quantity of compressed air that passes through a section over a unit of time. It is represented in l/min, m3, at the equivalent value in free air in conditions of standard reference atmosphere (SRA), i.e. +20 c, 65% of relative humidity, 1013 mbar, in accordance with norms NFE.

Common Brands[edit]

In addition, many store brands exist, such as those carried at Princess Auto, Summit Tools or Harbor Freight Tools.
