The MAROT Model BD vacuum is used for simple “in-circuit” removal. The grains are distributed in a uniform flow curtain through which air is sucked in.
The proportion of light impurities raised from the grains is adjusted by varying the airflow through a flap that allows outside air to bleed into the upper chamber before the fan.
Given its small overall size, the BD vacuum pre-cleaner can be easily inserted into a drying or grain treatment line.
