Plastic Pall Ring

The pall ring is greatly improved on the Laci ring. Although the outer diameter of the ring is also equal to the height, two rows of windows with inner tongue are opened on the ring wall. Each window hole has 5 tongue pieces. This structure improves the gas-liquid distribution and makes full use of the inner surface of the ring. Compared with Laci ring, the treatment capacity can be more than 50% and the pressure can be reduced by half.
