Page 6: Operating Principles
Operating Principles The Vacuum Excavator works on the principle of air velocity in order to produce suction at the end of the hose nozzle. Therefore if the end of the suction hose is fully plunged into either a solid or liquid no air flow will occur and there will be no suction. The vacuum system uses a 3 stage filtration system in order to filter dirt from the air stream. -
