™

Zeta Plus™Model ZPB sanitary filter housings provide the
ultimate standard for totally-enclosed Zeta Plus cartridge
filtration systems. Constructed from mirror polished 316L
stainless steel, Zeta Plus ZPB filter housings meet the ex­acting sanitary quality standards of the pharmaceutical,
food and beverage, fine chemical, and microelectronics
industries.

Standard Zeta Plus ZPB filter housings accommodate
from one to four 8", 12", or 16" diameter standard Zeta
Plus filter cartridges to offer a wide choice of filter media
area and flow rates.* Multiple cartridge housings can be
user fitted with shorter center-posts to accommodate
fewer cartridges.

3M Purification Inc. Zeta Plus filter housings are available
in a wide range of customized formats, including certifi­cation to ASME and other code certifications,
multi-cartridge, multi-round housings, and fully auto­mated filter skids and carts. Consult 3M Purification Inc.
for assistance on specialized Zeta Plus filter housings.

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.
