ROSave.Z

Summary

Product identification

ROSave.Z* is a Z.Plex* technology depth filter engineered specifically for reverse osmosis pretreatment and suitable for many pure water applications. It features a thermally bonded construction and mel-bonded end adaption.

Features and Benefits

• Engineered specifically for reverse osmosis pretreatment and suitable for many pure water applications
• Depth filter traps particles throughout the media
• True depth media offers longer filter lifetime
• Very low pressure drop and flow resistance
• Thermally bonded construction and mel-bonded end adaption

Applications

• Reverse osmosis pre-filtration for Veolia RO systems and universal equipment
• Beverage
• Electronics
• Pre/post DI or active carbon

Specifications

Micron Ratings

• Nominal Ratings: 1, 5 microns
• Efficiency of nominal filters varies by application. Nominal-rated filters have a wider distribution of pore sizes and rejected particle sizes, primarily used to compare efficiencies across filter families and between manufacturers. Efficiency depends on particle shape, size, composition, application, and testing protocol.

Efficiency Information

Table 2 in the official PDF provides removal efficiency based on a modified ASTM 795 test procedure, showing removal ratings (µm) at 90.0%, 99.0%, and 99.9% efficiencies for 1 µm and 5 µm filters. See the official PDF for exact tabulated values.

Clean Water Flow Rate

Graph 1 in the official PDF illustrates the clean water flow rate based on a 10 in length filter for both 1 µm and 5 µm filters, showing differential pressure (psi, mbar) versus flow rate (gpm, lpm). See the official PDF for the graphical data.
