A machine for distributing blowing insulation including a shredding chamber having an outlet end, a plurality of shredders configured to shred and pick apart the blowing insulation, and a discharge mechanism mounted at the outlet end of the shredding chamber and configured for distributing the blowing insulation into an airstream. The discharge mechanism includes housing and a plurality of sealing vane assemblies mounted for rotation. The sealing vane assemblies are configured to seal against the housing as the sealing vane assemblies rotate. The housing includes an eccentric segment extending from the housing. A blower is provided and configured to provide the airstream which flows through the discharge mechanism. The sealing vane assemblies become spaced apart from the housing as the sealing vane assemblies rotate through the eccentric segment.
