Plastic Pall Ring
NAIKE Plastic Pall Ring is versatile. This product was advanced on the basis of Plastic Rasching Ring, and compared with it, both of them have similar cylindrical dimensions but the Plastic Pall Ring has two rows of punched out holes, with fingers or webs turned into the centre of the cylinder, which significantly increases the performance of the packing, in terms of throughput, efficiency and pressure drop.
