Pneumatic tools are driven by compressed air, typically supplied at 6–7 bar (87–100 psi) through a centralised compressor network. A Filter-Regulator-Lubricator (FRL) unit at the point of use conditions the supply. Power output is governed by supply pressure (bar), Free Air Delivery (FAD) capacity of the compressor (l/s or cfm), and the tool's displacement volume and porting geometry.
The energy conversion efficiency of a typical reciprocating or rotary-vane air motor is in the range of 15–25% at the tool, with the overall wall-to-tool system efficiency considerably lower once compressor losses and distribution losses are accounted for. The key operational advantage is sustained peak torque delivery that is decoupled from usage duration — the tool performs consistently provided line pressure is maintained.
Compressed air is generated by a central compressor and distributed through a pipe network to points of use. At the tool, air expands through the motor, converting pressure energy into mechanical work.
System performance depends on maintaining stable pressure and sufficient flow throughout the distribution network.
Performance of pneumatic tools is highly dependent on the design and condition of the compressed air system. Pressure losses in pipework, leaks, and inadequate compressor capacity can all reduce tool effectiveness.
Proper system design and maintenance are essential to achieve consistent and reliable performance in industrial applications.

Pneumatic tools use compressed air to drive an internal motor, converting pressure energy into mechanical motion.
Most pneumatic tools operate at 6–7 bar (87–100 psi), depending on the application and tool design.
FAD is the volume of air supplied by a compressor and determines how many tools can operate effectively at the same time.
Clean, dry air prevents corrosion, reduces wear and ensures consistent tool performance.
