MAX-LOAD™
pleated filter bags are manufactured from the same polypropylene or
polyester needle felt material which
DURAGAF filter bags are
made from and they are formed into a pleated cylinder to
maximize surface area. MAX-LOAD filter bags have the
greatest amount of surface area of any filter bag and they
are used for minimizing the frequency of filter bag
replacements. Reduced the frequency of change-outs
also reduces labor costs, exposure to liquid and the
quantity of filter bags to be inventoried and disposed.
MAX-LOAD
pleated filter bags are manufactured from
silicon-free fibers under ISO 9001:2015 quality control standards to
ensure consistent performance.

Filter Bag Design
Coreless MAX-LOAD Filter Bag Design
The standard MAX-LOAD filter
bag has an internal core made of the same material as the
DURAGAF filter bag (polypropylene or polyester) which
undergoes a treatment process virtually eliminating
potential of fiber migration while remaining free from silicone
and other crater-forming substances.
All seams and
connections to the sealing ring are thermo bonded (welded)
to maximize the durability of the MAX-LOAD filter bag.
The internal core provides support akin to a filter bag
positioner, protecting the filter bag form downstream
pressure pulses often related to higher system pressures.
MAX-LOAD
pleated filter bags utilize a flexible crush ring seal to form both a chemically resistant
and bypass-free seal which improves as the differential
pressure increases. The sealing ring has integrally molded handles
to simplify removal from the vessel. and due to a special
surface. MAX-LOAD filter bags are provide for both #1
and #2 size filter bag vessels.
The
coreless version of MAX-LOAD filter bags have the look and
feel of a filter cartridge however the flow path remains
from inside-to-outside and thus particles are retained when
removing the filter bag from the vessel. Unlike the
other MAX-LOAD filter bags, the coreless version is made
from polypropylene or polyester melt-blown materials; the
same materials used for our absolute rated filter bags
CLEARGAF, ACCUGAF and PROGAF. They are constructed of
multiple layers, each graded for increasingly fine particle
retention, resulting in a wall thickness of about 0.7".
They are available with a 10 micron nylon monofilament mesh
cover for fiber sensitive applications.
Why
Go Coreless?
Whereas MAX-LOAD pleated filter
bags maximize filter area to decrease filter bag change-out
frequency, the coreless version only has 82%
less surface area (even
less surface area then a standard filter bag), so they are
used:
to provide maximum depth filtration for higher pressure applications that would otherwise require filter bag positioners to restrict filter bag movement
Retention of gelatinous/deformable particles
