HY-PAK® Random Packing

An improved alternative to FLEXIRING® or Pall-type ring packing.
An improvement to the FLEXIRING packing geometry is in the HY-PAK® random packing, introduced to the market in the late 1960s. Maintaining a 1:1 aspect ratio, the number of fingers were doubled. The mechanical strength was enhanced through the introduction of circumferential stiffening ribs. The new geometry allowed the rings to be made slightly larger, effectively providing a new packing with increased capacity, reduced pressure drop, and no noticeable reduction in efficiency. HY-PAK packing is widely used as a direct replacement for FLEXIRING or Pall ring random packings of equivalent size in many applications to gain capacity or reduce pressure drop.
