Section 3 - Operation
3.1 Principles of Operation
The Brandt Grain Vac 5000 uses a centrifugal fan to produce a vacuum inside a hollow body. This vacuum
creates a flow of air that conveys granular materials to the body. Once in the body of the machine, the grain
is removed by an auger and the air is drawn from the body by the centrifugal fan. The auger discharges the
grain into the awaiting transport through an airlock door. The airlock door ensures suction from the inlet
hoses only. The air, once drawn from the body, passes through the fan and is discharged through an
exhaust pipe.
The centrifugal fan is belt driven by the tractor PTO. The discharge auger position is controlled by tractor
hydraulics and the flighting is chain driven by the tractor PTO.
