When sourcing a 10HP compressor, the most critical factor is the Actual Free Air Delivery (FAD), which should typically range between 35-45 CFM (1.0-1.2 m³/min) depending on the pressure. Ensure the 300L tank is ASME or CE certified for pressure safety, featuring a wall thickness capable of handling at least 12.5 bar (180 PSI) even if your working pressure is lower. Additionally, verify the motor insulation class (Class F recommended) and IP54/55 protection rating to ensure durability in industrial environments.
