Machine Overview

Operating Principles
The Vacuum Exca ator works on the principle of air elocity 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 acuum system uses a 3 stage filtration system in order to filter dirt from the air stream.
Firstly solid or liquid material is drawn into the air stream at the end of the suction hose and
tra els to the collection tank. Due to a sudden change in olume in the tank, the air speed
dramatically drops and the solid or liquid material falls out of the air stream into the collection
tank.
Second filtration is by cyclone to remo e any course dust particles.
Then the third and final stage remo es dust from the airstream ia a cartridge type air filter.
Air flow through the whole air circuit is important to ensure that suction is maintained. It is
critical not to o erload the filters in the air stream circuit. This is best achie ed by not sucking
dry material into the machine. Therefore always use water to break up the ground to be
sucked away by using the in-built water blaster.
The “No-Dig” action of the machine is achie ed by firstly wetting, loosening and breaking up
tight hard ground with the water blaster and then sucking away the loosened ground with the
acuum hose. The machine is primarily designed as a two person operation where one
person is performing the water blasting operation whilst the other is acuuming away the
loosened material.
The primary design intent of the machine is to loosen and suck away ground and small rocks
around buried ser ices or in tight work areas.
The machine is not designed or intended to for acuuming toxic or hazardous material. In
case of accidental contact with toxic or hazardous material use appropriate dumping and
clean out procedures.
