The CUNO High Flow Filtration System is an advanced design that uses 3M Innovation and CUNO’s extensive
filtration experience to deliver a high flow filter in a compact housing design. When compared to conventional
cartridge systems, this system provides the following advantages:
The construction of CUNO High Flow Filters permits flow rates of
up to 500 gpm in a single cartridge. The result? Fewer filter
elements to accommodate your flow requirements. In fact, the
CUNO High Flow Filtration System requires as few as one-tenth
the number of elements as competitive 2.5” pleated cartridges (see
Figure 1).
Using fewer elements combined with an outside-to-in flow path
enables a reduction in the size of housing required for your
application. The CUNO High Flow Housing takes up as little as
one-half the size of competitive housings for a given flow rate.
The result is lower capital investment costs and a compact
footprint that saves valuable plant space (see Figure 1).
The CUNO High Flow Filtration System is designed
with ease-of-use in mind. From a user-friendly,
ergonomically designed handle that makes cartridge
installation and removal easier without the use of
special tools or other hardware, to a "twist-to-lock"
cartridge seating mechanism that provides a positive
seal, the CUNO High Flow System facilitates easy
operation and maintenance of your filter system.

CUNO High Flow Filters are designed using state-of-the-art
technology, optimizing both performance and effluent quality to ensure
customer satisfaction. The elements use a pleat design that results in a
high usable filtering surface area per filter.
3M Innovation is at the heart of the CUNO High Flow Filter. A
compound radial pleat design maximizes the usable surface area per
filter. Blown microfiber forms the basis of the filter media, which is
made to tightly controlled fiber diameter specifications to produce a
media with absolute rated particle retention characteristics. Our
manufacturing process embosses the media to produce a more uniform
pleat pattern, which, in turn, allows greater utilization of the media by
evenly distributing the fluid throughout the entire filter structure. This
results in consistent particle retention in a compact, space-saving
design.
The CUNO High Flow Filter contains several features to combine high
performance with easy operation.
+ A large diameter
core allows up to
500 gpm through a
single filter
element.
+
An ergonomically
designed handle
has been designed
to facilitate fast
and easy insertion
and removal
without the use of
special tools.
Cartridges are
simply inserted
over a built-in
guide tube.
+
The seating
mechanism uses a
“twist to lock”
design to provide a
positive seal.

- Each grade of the CUNO High Flow Filter is manufactured from meltblown FDA compliant
polypropylene microfiber media, providing high particle removal efficiency with broad chemical compatibility. No
adhesives, binders, or silicone are used in the manufacturing process. The raw materials composing these filters are
FDA compliant according to CFR Title 21. All support layers and hardware are constructed with polypropylene.
- O-rings are available in a variety of materials to suit your applications, including the standard nitrile,
Ethylene Propylene Rubber (EPR), silicone, and fluorocarbon.
