Compressed air, normally 80-100 PSlG (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, debris or other particulate can then be exhausted into a filter bag or hose attached to the Deep Hole Vac-u-Gun System.
The Deep Hole Vac-u-Gun should not be operated without a filter bag or vacuum hose attached to the exhaust. Vacuum tools can not be used with this product.
