  • TwinPower Turbine | MORITA

    The ABSD builds up air pressure thanks to the centrifugal force engendered by rotation. The rotation and centrifugal force enable the air to flow into the ASBD, where it remains compressed – even after the drive air ceases to flow. The compressed air in the ASBD is expelled on the lower side of the head.
