Under different spray gun nozzles and pressures, the air flow varies slightly:
For example, when using a 5.0–6.0mm nozzle spray gun to clean an engine combustion chamber, at 0.8 MPa pressure, the air flow is about 1.0–1.6 m³/min.
The air compressor should have a power of 7.5 kW (10 HP) and be paired with an air tank of over 250 L.
