  2. Jackhammer - Wikipedia

    en.wikipedia.org/wiki/Jackhammer

    Hand-held jackhammers are generally powered by compressed air, but some are also powered by electric motors. Larger jackhammers, such as rig-mounted hammers used on construction machinery, are usually hydraulically powered. These tools are typically used to break up rock, pavement, and concrete.

  3. Pneumatic tool - Wikipedia

    en.wikipedia.org/wiki/Pneumatic_tool

    A pneumatic tool, air tool, air-powered tool or pneumatic-powered tool is a type of power tool, driven by compressed air supplied by an air compressor. Pneumatic tools can also be driven by compressed carbon dioxide (CO 2) stored in small cylinders allowing for portability. [1] Most pneumatic tools convert the compressed air to work using a ...

  4. Compressed air - Wikipedia

    en.wikipedia.org/wiki/Compressed_air

    Compressed air is an important medium for the transfer of energy in industrial processes and is used for power tools such as air hammers, drills, wrenches, and others, as well as to atomize paint, to operate air cylinders for automation, and can also be used to propel vehicles. Brakes applied by compressed air made large railway trains safer ...

  5. Underground pneumatic boring - Wikipedia

    en.wikipedia.org/wiki/Underground_pneumatic_boring

    A piercing tool uses compressed air to bore through the ground. Manufacturers have proprietary standards and control mechanisms. Compressed air is run to the piercing tool through a pneumatic hose. Additionally an oiler attachment is used to send oil along with the compressed air, similar to a jackhammer. Inside the piercing tool is a piston. A ...

  6. Work in compressed air - Wikipedia

    en.wikipedia.org/wiki/Work_in_compressed_air

    Traditionally, compressed air work was limited to maximum ambient pressures of between 3 and 4 bars (3.0 and 3.9 atm), but experience with offshore saturation diving shows that higher pressures can be managed at acceptable risk using the techniques developed in that industry, including saturation exposures and the use of breathing gases other than air.

  7. Air compressor - Wikipedia

    en.wikipedia.org/wiki/Air_compressor

    Air compressor supplies air into a nail gun.. An air compressor is a machine that takes ambient air from the surroundings and discharges it at a higher pressure. It is an application of a gas compressor and a pneumatic device that converts mechanical power (from an electric motor, diesel or gasoline engine, etc.) into potential energy stored in compressed air, which has many uses.
