The present document shows a separator for separating granular material, such as seed, fertilizer or pesticide, from a material-laden airflow (FI). The separator comprises a separator zone (Z) having an inlet (11) for a material-laden airflow, a material outlet (13) and an air outlet (12, 12&prime), and at least two separator parts (15, 15&prime), which extend only substantially along a material flow (FM) in the separator zone (Z) and between which is formed a separator gap (12, 12&prime), which is sufficiently narrow to allow air, but not the granular material, to pass through it. At the material outlet (13), the separator gap (12, 12&prime) is at least partially open, viewed in a direction which is substantially parallel with the material flow (FM), so that material which gets stuck in the separator gap (12, 12&prime) is allowed to leave this by means of displacement principally along the material flow (FM).
