AirVac — a new generation of vacuum metering units
The AirVac metering unit is universally applicable for precision sowing of various crops. It can be fitted with metering discs for corn, sunflower, sugar beet, soybean and rapeseed.
The AirVac vacuum system uses the pulling force to hold grains/seeds against the holes in the metering disc. A singulator located inside the metering unit prevents doubles from being picked up and metered. The key feature of the AirVac seed singulator is that it requires no fine adjustment at all. The singulator’s special shape allows it to work with seeds of different sizes and grades.
Through the coulter tube, the AirVac metering unit guides the grain/seed into the furrow. To monitor sowing quality, a sensor is installed in the tube for each row, letting you count the number of seeds and record the distance between where they’re placed, so the operator is informed promptly of any doubles or skips.
The information obtained is instantly displayed on the terminal’s monitor in an easy-to-read format.
The AirVac metering unit has an electric drive with individual control. This technology forms the basis for using functions such as SectionControl, VariableRate or controlled traffic farming management.
With VariableRate, the AirVac system can change the seeding rate in an individual row. In the case of a technological track, the seeding rate can be changed in the rows adjacent to it. These innovative functions can be used extensively to increase sowing precision.
