What does pneumatic mean?
From the Greek ‘pneuma’ meaning air or breath. In technical terms: powered by compressed air. A pneumatic system converts compressed air into mechanical motion or force.
A compressor pressurises air in a receiver. Via hoses and couplings, the compressed air flows to the tool. When the trigger is pressed, air flows into a small motor or cylinder that drives the tool. After use, the air leaves through an exhaust port.
No battery or electric motor inside the tool. The power comes from the external air supply. Pneumatic tools are significantly lighter, reducing operator fatigue.
Pneumatic tools produce no sparks. In environments with flammable vapours this is a safety requirement, not a preference. Many models are ATEX certified under directive 2014/34/EU.
Air cools the tool continuously from within. Pneumatic equipment can be used for hours without thermal problems.
Fewer moving parts. No carbon brushes, no battery cells to wear out. Periodic lubrication is typically sufficient.
| Criterion | Pneumatic | Electric | Battery |
| Power per kg of weight | Highest | Medium | Lower |
| ATEX suitability | Inherent (no sparks) | Special version required | Special version required |
| Overheating | Impossible | Risk during prolonged use | Risk under overload |
| Tool weight | Lowest | Medium | Heaviest (battery) |
| Maintenance | Minimal | Brushes, cooling | Battery, cooling |
| Mobility | Limited by hose | Limited by cable | Fully free |
| Laco applications | Offshore, petrochemical, shipbuilding | Assembly, construction | Hard-to-reach locations |
Offshore and petrochemical: ATEX zones 1 and 2 — electric tools without special certification are not permitted. Pneumatic equipment is the standard. Shipbuilding: lightweight and powerful for bolting, grinding and flange machining. Machinery and assembly: precision torque wrenches for production lines.

For heavy industrial applications and ATEX environments: yes. Lighter, more powerful per kg, spark-free and cannot overheat. For lighter tasks with power available, electric may be more practical.
A compressor delivering sufficient pressure (6-7 bar) and air flow in litres per minute as specified for the tool.
