A pneumatic drive is a system that uses compressed air to create motion and power machinery. It operates by converting the energy from compressed air into mechanical energy, which can be used to drive various tools and equipment. This technology is commonly found in industries such as manufacturing and construction, where it powers devices like air tools and cylinders. Pneumatic drives are favored for their simplicity, reliability, and ability to provide high force in a compact design. They are also safer than electric drives in certain environments, as they reduce the risk of sparks and electrical hazards. Overall, pneumatic drives play a crucial role in automating processes and enhancing productivity.
