The Next Generation in Pharmaceutical Depth Filter Technology
Enhanced flow. Lower pressure drop. Extended service life and lower total filtration
costs…these are the benefits of Betapure™ NT-P Series filter cartridges & capsules, the
latest advance in depth filtration technology. The all polypropylene filter is constructed
using a process that utilizes flow enhancing filter media and an innovative flow pattern.
The result is an absolute-rated filter with vastly superior life that provides more cost effective filtration than conventional polypropylene depth filters. Betapure NT-P Series filter
cartridges - the new leader in filtration performance.
Betapure NT-P Series Filter Construction
Betapure NT-P Series cartridges and capsules are designed to provide significantly
superior service life while maintaining a consistent filtration efficiency. They achieve this
through an innovative design that allows uniform distribution of fluid flow and contaminant throughout the entire depth of the filter. Betapure NT-P Series filter construction
combines a unique 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 (see Figure 1).
Figure 1: Betapure NT-P 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-P Series pharmaceutical grade 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-P Series
filters. The result is significantly shorter service life, and unpredictable filtration efficiencies. In this case, Betapure NT -P Series 5 micron filters provide a service life improvement of up to 2 times greater than competitive products. (Graph 1)
Lower Pr essur e Drop
The unique design and construction of the Betapure NT -P Series cartridge allows for significantly lower pressure drops compared to equivalently rated polypropylene depth filters. Based on published data, a 5 micron Betapure NT-P Series filter system with a given
flow would use up to 50% fewer cartridges than a 5 micron Pall® Profile. To underscore
the Betapure NT-P Series filter cost benefit, use the example in Table 1 as a guideline.

For the same initial cartridge differential pressure, a 110 gpm system using Betapure
NT-P Series 5 micron filters require significantly fewer, less than half, cartridges. This
results in lower capital investment for the filter housing and fewer cartridges to purchase.
The Confi dence of Consistency
Betapure NT-P 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-P Series filter’s consistent performance,
as illustrated by comparative Beta-Ratio vs. Differential Pressure (Graph 2), provides
predictable results throughout the filter’s usable life. F ilters A, B, and C show a degradation in the Beta-Ratio as the differential pressure 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-P Series
Consistent filtration performance, time after time, from start to finish - the goal of every
filter user, the solution provided by Betapure NT-P Series filters. Absolute removal
ratings for Betapure NT-P Series filters are determined using a filter performance test
developed by 3M Purification Inc. to comply with the general procedures outlined 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 -P Series filter ratings are specified in Table 2.
Your Benefi t - Total Filtration Cost Reduction
The Betapure NT-P Series filter’ s performance and superior life advantage allows direct
cost savings by reducing the number of filters used. In addition, the resulting reduction
in filter change-out frequency decreases direct labor and filter disposal costs. Betapure
NT-P Series filter cartridges - providing performance and value.
