The Bauer ring is a major improvement on the Rassi ring, although the outer diameter of the ring is also equal to the height, but two rows of windows with intruding tongues are opened on the ring wall, and each window hole has 5 tongues. This structure improves the gas-liquid distribution and makes full use of the inner surface of the ring. Compared with the Lassi ring, the processing capacity can be more than 50% larger, and the pressure can be reduced by half; It is generally made of metal, plastic or ceramics.

Bauer ring packing has the advantages of large flux, low resistance, high separation efficiency and high operating flexibility, and the processing capacity can be more than 50% larger than that of the Rassi ring under the same pressure reduction. At the same throughput, the pressure reduction can be reduced by half, and the mass transfer efficiency can be increased by about 20%. Compared with the Lassi ring, this packing has the characteristics of large production capacity, small resistance, large operating elasticity, etc., under normal circumstances, the same pressure drop treatment can be 50%-99% larger than the Lassi ring, the same treatment pressure drop is 50%-70% smaller than the Lassi ring, the tower height also has a pressure reduction, the use of Bauer ring can be about 20%-40% of the packing volume than the Lassi link.
