To evaluate the suction power of an industrial vacuum cleaner, several key parameters must be considered, which together provide a complete picture of its performance:

• Vacuum (or Static Pressure): Measured in mbar or kPa, it indicates the vacuum’s ability to create negative pressure and lift heavy materials or overcome resistance (e.g., long hoses, dirty filters). A high value is essential for suction of chips, dense liquids, gravel, or applications that require strong “pulling power.”
• Airflow (or Flow Rate): Measured in m³/h or L/s, it indicates the volume of air moved. High airflow is crucial for quickly removing large amounts of fine or light dust, fumes, or for efficiently covering wide surfaces.
• Motor Power (kW or HP): Although not the only factor, higher motor power generally allows for higher vacuum and airflow performance.
• Filtration System Efficiency: A good filter maintains suction performance over time and ensures clean exhaust air.
• Application Type: The ideal “power” depends on the material being vacuumed (liquids, solids, fine dust, heavy debris) and the system complexity (hose length, number of suction points).
