All vacuum insulation pipeline insulation pipeline cleaners operate based on air flowing from the opening at the cleaning head or tool, through the vacuum cleaner and the bag and/or filter system and then out the exhaust port. This airflow is created by the vacuum motor, which also may be referred to as the suction motor.
The vacuum motor consists of electrical components attached to a fan or multiple fans. When the fans spin, a partial vacuum is created and the pressure inside the vacuum cleaner drops below the ambient air pressure in the room. Because air pressure is higher outside the vacuum cleaner than inside, air rushes through the vacuum cleaner.
The maximum amp “draw,” (the number of amps the vacuum cleaner uses when running) allowed for any appliance that plugs into a standard household outlet is 12. Therefore, if you see amperage ratings above 12, read the fine print, as they are not true amperage specifications but some other manufacturer developed “performance rating” designed to create the impression of a more powerful vacuum systems suppliers cleaner.
