Betapure™
NT-T Series
The Next Generation in Depth Filter Technology
Betapure™ NT-T Series filter cartridges are 3M Purification Inc.’s latest advance in
depth filtration technology. The all polypropylene filter is constructed using a design
that utilizes flow enhancing filter media and an innovative flow pattern. The result is an
absolute-rated filter with vastly superior on-stream life that provides more cost effective
filtration than conventional melt-blown filter technologies. Betapure NT-T Series filter
cartridges - the new leader in filtration performance.
Betapure NT-T Series Filter Construction
3M Purification Inc. designed the Betapure NT -T Series cartridge to provide significantly
superior service life while maintaining a consistent filtration efficiency . Betapure NT-T
Series filters achieve this through an innovative cartridge design that allows uniform
distribution of fluid flow and contaminant throughout the entire depth of the cartridge.
Betapure NT-T Series filter construction combines a polypropylene media with fluid distribution netting to form multiple layers. Critically positioned media flow channels allow
greater movement of fluid from layer to layer. Three distinct media sections, made from
multiple media/netting layers, are combined to form the filter cartridge.
Figure 1: Betapure NT-T Series Media Sections. Note that the actual fi lter sections contain multiple layers of media.

The outer and middle sections contain multiple layers of interleaved filter media and
fluid distribution netting. Within each media layer a portion of the fluid travels through
the media while the balance of the fluid is delivered directly to the next distribution
layer through the flow channels. The fluid distribution netting provides longitudinal and
latitudinal flow paths to evenly distribute fluid flow across the surface of each successive
media layer.
The Difference is Performance
Flow channels appear in the outer and middle sections of the filter matrix, as seen in the
cartridge cut-away. The size, number, and location of the flow channels combined with
the fluid distribution netting ensure that a uniform amount of contaminant is distributed
to each layer within these two sections, while maintaining a consistent flow.

The number of media flow channels decrease from the outer to middle sections to ensure
even contaminant loading throughout the entire filter matrix. Extensive laboratory testing has demonstrated that 3M Purification Inc. has developed the optimal filter cartridge
design.
The inner section, supported by a rigid polypropylene core and equal to approximately
one third of the filter’s depth, contains no flow channels and is the final qualifying section
ensuring absolute rated performance.
The even distribution of contaminated fluid throughout the depth of the cartridge is the
key to the Betapure NT-T Series filter’ s exceptionally long service life, low pressure
drops, and increased cost effectiveness.
The Result
Superior Filter Service L if e
Extensive testing has demonstrated that competitive filters of equivalent removal ratings
subjected to the same contaminant load plug more quickly than Betapure NT-T Series
filters. The result is significantly shorter service life, and unpredictable filtration efficiencies. Betapure NT -T Series filters provide a service life improvement of up to 3 times
greater than competitive products. (Graph 1 )
Lower Pr essur e Drop
The design and construction of the Betapure NT-T Series cartridge allows for significantly lower pressure drops compared to equivalently rated polypropylene depth filters.
Based on published data, a Betapure NT-T Series filter system with a given flow would
use up to 75% few er cartridges than Osmonics Selex, 68% fewer than Pall® Profile , an d
42% fewer than Pall® Nexis. T o underscore the Betapure NT-T Series filter cost benefit,
use the example in T able 1 as a guideline.

NT-T Series filters require significantly fewer cartridges. This results in lower capital
investment for the filter housing and fewer cartridges to purchase.
The Confi dence of Consistency
Betapure™ NT-T Series filters utilize advanced design and construction to achieve a
level of filtration consistency unattainable by competitive filters. Combined with an
exceptionally long service life, the Betapure NT-T Series filter’s consistent performance,
as illustrated by comparative Beta-Ratio vs. Differential Pressure (Graph 2), provides
predictable results throughout the filters’ usable life. Filters A, B, and C show a degradation in the Beta-Ratio as psid increases. These filters exhibit a pattern of either
unloading previously held particles or a loss of filtration efficiency. The result of this
inconsistent performance is a reduction in finished product quality, product yield, and
an increase in total filtration cost.
Absolute Betapure NT-T Series
Consistent filtration performance, time after time, from start to finish - the goal of every
filter user, the solution provided by Betapure NT-T Series filters. Absolute removal
ratings for Betapure NT-T Series filters are determined using a filter performance test
developed by 3M Purification Inc. to comply with the general procedures outlines in
ASTM STP 97 5. 3M Purification Inc. defines absolute rating as the particle size (x)
providing an initial Beta Ratio (Bx) = 1000. At this Beta Ratio, the removal efficiency
is equal to 99.9%. Betapure NT -T Series filter ratings are specified in Table 2.
