Make smarter
air-tool decisions.
Choose the right pneumatic tool, match it to the right compressor and avoid expensive airflow mistakes—with practical guidance built for real workshops.
What do you need to work out?
Do not buy an air tool from one headline number.
| Tool family | Compare first | Air-demand pattern | Common mistake | Decision support |
|---|---|---|---|---|
| Impact wrench | Working torque · drive size · mechanism · weight | Intermittent, high-load bursts | !Buying on breakaway torque alone | Torque + compressor check |
| Angle grinder | Wheel size · horsepower · RPM · reach | Sustained, air-hungry use | !Ignoring airflow and wheel limits | Material + duty selector |
| Random-orbit sander | Pad · orbit · vacuum mode · vibration | Long continuous cycles | !Undersizing the compressor | Finish + abrasive matcher |
| HVLP spray gun | Nozzle · inlet PSI · CFM · feed type | Stable flow and clean, dry air | !Using tank gallons as the main test | Nozzle + air-quality check |
Use the checker below. If you only have tank gallons or maximum PSI, start with compressor sizing.
Will your compressor actually run the tool?
A tank size alone cannot answer that question. Start with airflow at the stated pressure, then account for how the tool will really be used.
- 01Compare SCFM at the same PSI
- 02Allow for trigger time and duty cycle
- 03Check hose and coupler restrictions
Compressor compatibility
Air supply appears adequate. Hose size and pressure at the tool still matter.
Preliminary guidance only. The full checker will also use tank size, hose length, fittings and simultaneous demand.
Start with a real workshop question.
Can a 6-gallon compressor run a 1/2-inch impact wrench?
