Recommended flow rates are based on ½ GPM /ft2of media installed. Actual flow
rates may vary based on many factors such as medium type, temperature, viscosity and contamination level of the fluid being filtered, and housing connections.

Filter Housing Flow Rates
Filter housing flow rates are dependent on the nature of
the application. Variables such as filter media formulation
and grade, temperature, viscosity, and the contamination
level of the fluid all will dictate the ideal flow rate. Consult with 3M Purification Inc. representatives for ideal
system rates for your application.
Zeta Plus Depth Filters
Zeta Plus depth filters are a family of filtration media
composed of high surface area inorganic filter aids embedded in a cellulose fiber matrix. During the
manufacturing process, molecules carrying a positive
charge are chemically bonded to the matrix components,
permanently forming an interconnected, rigid filter sheet
with positively charged electrokinetic capture sites capable of retaining bacteria, endotoxins, haze components,
cellular debris and submicronic contaminants to a level
which mechanical screening alone cannot achieve. Zeta
)
Plus filter cartridges are available in a variety of media
formulations and retention ratings designed to meet the
needs of the pharmaceutical, food and beverage, fine
chemicals, and micro-electronics industries. For more information about Zeta Plus media choices, please contact
3M Purification Inc..
Cartridge Sealing System
A spring-loaded sealing system (sealing nut shown below) provides optimal sealing compression to help
prevent filter bypass even under the most arduous process conditions.
