Plastic Super Intalox Saddle is a 25–76 mm random packing family that shifts from relatively high surface-area small models toward highly open larger models. Selection should consider mass-transfer requirements, hydraulic capacity, fouling, tower diameter and polymer compatibility, and comparisons with standard Intalox Saddle should be made using actual model-level technical data rather than product names.

Metal Flat Ring is a low-profile metal random packing available across a broad size range, from high-surface-area small elements to very open larger elements. Selection should balance mass-transfer requirements, hydraulic capacity, fouling, tower diameter, material compatibility and the verified specifications of the actual Flat Ring size.

Ceramic Cross Partition Ring is a random packing with a cylindrical ceramic body and cross-shaped internal partitions. It can provide additional gas-liquid contacting surface in corrosive and high-temperature services, but selection should balance hydraulic openness, fouling risk, ceramic compatibility, packing size, bed weight and tower-support requirements.

Plastic Polyhedral Hollow Ball is a multi-size random packing with an open hollow framework and substantial gas-liquid contacting surface. Selection should balance surface area, hydraulic openness, fouling tolerance, tower diameter and polymer compatibility, and final procurement should use the approved product datasheet rather than nominal size alone.

Plastic Lanpac is a random packing family available in DAIER's verified database in 60 mm and 90 mm classes. The 60 mm model provides substantially greater specific surface area, while the 90 mm model provides greater void fraction and lower bulk density, creating a meaningful mass-transfer-versus-hydraulic-openness selection decision.
