MACHINE COMPONENTS*

The air pumps or blowers are the key components in the Grain-Vac and are driven by the tractor PTO
through a belt drive system. The blower moves air through the machine. On the intake side, the blower
creates a vacuum in the receiver tank and intake lines for picking up grain. Grain is separated from the
stream of air in the receiver tank.
On the discharge side of the blower, the pressurized air flows through the airlock where it picks up a
metered quantity of grain and moves it out the lines to the discharge cyclone.
The airlock is rotated with hydraulics powered by the same power source as the blower. A hydraulic
cylinder or boom jack lifts the discharge boom for positioning.
