Pneumatic tools are powered by compressed air. This compressed air is typically supplied by an air compressor, which converts electrical or gasoline power into compressed air stored under pressure. The compressed air is then delivered to the pneumatic tool through an air line, where it drives a pneumatic motor or piston to perform mechanical work such as drilling, grinding, nailing, or hammering

. Key points about pneumatic tools and their power source:

• The primary power source is compressed air, usually at pressures around 4 to 6 bar (about 60 to 90 psi)

• Compressed air is generated by an air compressor, which can be powered by electricity or gasoline engine

• Some pneumatic tools can also be powered by compressed carbon dioxide (CO2) stored in small cylinders for portability

• Pneumatic tools convert the energy of compressed air into mechanical motion, either rotary or linear, depending on the tool design

• Compared to electric tools, pneumatic tools are lighter, safer (no risk of electric shock or sparks), and often more durable under heavy use

In summary, pneumatic tools are air-powered tools that rely on compressed air supplied by an air compressor or compressed gas cylinders to operate effectively and safely
