In industrial vacuum systems, “suction power in Pa” (Pascal), or more commonly in mbar (millibar) or kPa (kilopascal), refers to the vacuum pressure or negative pressure the vacuum can generate. This parameter indicates the unit’s ability to lift and move materials—even heavy ones—through the piping system. A higher value in Pa/mbar/kPa means stronger suction and better capability to handle heavy loads or longer distances.
