Single hopper
The single hopper machines are equipped with
an injector nozzle in the fall sluice.
In the sluice the seed is injected into the air flow.
A foldable lid is mounted to the underside of
the fall sluice, which is opened for calibration.
The calibration bag can then be hooked into the
hooks on the housing.

the fan is split before the metering units.
