Air compressors are integral components in pneumatic systems. There are advantages as well as disadvantages of requiring an air compressor for power. Air compressors can be transported to areas that are not readily connected with the local power grid. However, air compressors can be extremely heavy, which can make it difficult to maneuver by hand. Air compressors can also be noisy, which is why you should use ear protection while working near active air compressors.
Pneumatic tools operate under high pressures. For this reason, hosing is employed in pneumatic systems. Pneumatic hosing must be resistant to crushing and abrasion. A ruptured pneumatic hose can leak high-pressured air into the environment. Air moving at such high speeds can easily pierce the skin. In Canada, the Canadian Center for Occupational Health and Safety recommends employing hosing that offers at least 1,035 kPa (kilopascal) working pressures for pneumatic tool applications. 0.145 PSI (pounds per square inch) is approximately equivalent to 1,000 Pascals.
Many tools that operate under compressed air are available to consumers. Pneumatic nail guns and pneumatic drill drivers are some of the most popular hand tools available. Pneumatic power washers can be used for many applications, from cleaning a boat to removing mud from a driveway. Consumers also have access to tools like jackhammers, sanders and buffers that all operate under compressed air. Pneumatic tools must be properly maintained and lubricated to remain effective. Improperly maintained and lubricated pneumatic tools are likely to jam or otherwise fail.
Pneumatic tools can easily injure their operator, so it's important to take the appropriate safety precautions. Steel-toed boots can help prevent foot injury from pneumatic nail guns that are accidentally discharged. Pneumatic tools are engineered to operate under a specific pressure range. Never use pneumatic tools under pressures that exceed those recommended by the manufacturer. Wearing goggles while using pneumatic tools will help prevent debris from injuring your eyes.
