Air tools, or pneumatic tools, use compressed air or gas to operate and include nail guns, drills, and paint sprayers. They are lighter, more powerful, and easier to use than electric tools. Air pressure can come from an air compressor or gas cylinders. Air tools can transfer power into high amounts of torque, allowing them to spin with great power. They are also used for chipping, cutting, and scraping materials. Paint sprayers, airbrushes, and pressure washers use compressed air to release paint or water onto surfaces. Sandblasters are even more powerful and can remove layers of surfaces.
Air tools, also called pneumatic tools, are mechanical tools that rely on compressed air or gas to operate. Types include nail guns, drills, paint sprayers, and other tools that come in a variety of shapes and sizes and are used for many different jobs. Air pressure tools are mostly found on professional job sites, but are also popular with DIY homeowners. These tools are generally lighter, more powerful, easier to use, and have fewer moving parts than their electric counterparts.
The compressed air or gas used to power air pressure tools can come from a mechanical air compressor and compressed gas cylinders. There is usually a tube connecting the instrument with the gas source. Larger industrial tools require a very powerful air compressor and heavy-duty hose, while some smaller varieties, such as DIY tools, may only require a small, low-power air compressor.
Most power tools are manufactured as air pressure tools as well as being available as power or non-power tools. One of the more common examples is the pneumatic nail gun, also called an electric nailer or pneumatic hammer. These tools have obvious advantages over using a hammer to drive nails because they are faster, more accurate and much more powerful. There are also pneumatic hammers available that use the power of compressed air for purposes other than driving nails, such as chipping, cutting and scrapping a wide variety of materials.
Air tools can also transfer their power into high amounts of torque, which allows them to spin with great power. These types include air sanders, air ratchets, and air impact wrenches, the latter of which typically have the ability to attach any number of accessories for different types of jobs. For example, you can connect screwdriver heads and sockets for powerful insertion and removal of screws and bolts, which can often be impossible to remove by hand.
Other air powered tools that take advantage of the powerful torque created by compressed air are air drills and tappers. Pneumatic drills can drill much more powerfully than electric drills; this may make it necessary for drill bits to be even stronger and made of denser metals. Similarly, air compressor tappers can drive screw holes into very hard surfaces with their high torque levels.
Other types of pneumatic tools use, in addition to pressure, a powerful release of compressed air. The most common examples are paint sprayers and airbrushes which can use compressed air to release paint onto a surface quickly, powerfully and evenly. Pressure washers work in a similar way and release water at very high rates to clean surfaces quickly and thoroughly with minimal operator effort. Even more powerful are sandblasters, which release steam along with tiny bits of sand that can actually remove layers of surfaces and are commonly used to remove paint, smooth surfaces, and roughen surfaces.
