Deep Hole Vac-u-Gun™ - How it Works

Compressed air, normally 80-100 PSIG (5.5 - 6.9 BAR), flows through the inlet (1) into an annular plenum chamber (2) when the trigger is depressed. A small amount of air is injected into the blow tube (3) to provide lift for the chips or debris. The larger airflow is injected into the throat of the gun through directed nozzles (4). These jets of air create a vacuum at the intake (5) which draws material in and accelerates it through the unit. The chips or other particulate can be exhausted into a filter bag or hose.
