Pall Polypropylene Filters
Selection Guide

Determining Operating Conditions
Selecting the appropriate filter requires knowledge of the application parameters.
The following information is required to guide the user.

1. Define the fluid
Type of fluid to be filtered: □ Gas □ Liquid (aqueous) □ Liquid (solvent)
Name of fluid to be filtered: _____________________________________________________________Name of solvent (if the fluid to be filtered is solvent-based) __________________________________
Presence/absence of solid content: □ Suspension (e.g.,slurry) □ Solution
Viscosity:______________________________ mPa･S
pH:______________________________
1□℉
Temperature : ______________________________ □ ℃
Pressure2 :______________________________ □ MPa □ kg/cm2
Note:

2

The maximum operating temperature for polypropylene is 80℃ /176℉. Contact Pall for higher temperature options.
The temperature and pressure of the gas to be filtered is required to determine the standard volume.

2. Determine the required removal rating
Removal rating: □ Nominalµm□ Absoluteµm
In-service filter: □ Existing □ N/AFilter part no.:_______________________________________________________________________
Note:
Determine the need for an “absolute” or “nominal” rating. If the removal rating of the current filter or a filter
used in a similar application is unknown, note the part number and contact Pall.

3. Determine the flow rate
Liquid flow rate:□ L □ m3 / □ minute □ hour □ batch
For batch filtration, processing time: ________________ □ minute □ hour1Select the Filter Medium and Configuration
Select the appropriate medium from the selection chart below, using the type of fluid to be filtered(viscosity, solids concentration) and removal ratings as a guide. If the fluid to be filtered is not listed, selectthe filter medium and configuration recommended for a similar type of fluid.

Characteristics of Polypropylene Media andApplications
Depth Media
Depth filters are constructed by depositing fibrous material onto a rotating center core and forming a tapered pore structure.
Four types of products are available.

■ Profile® Ⅱ Filter

Applications
These filters are the ideal choice to replace string
wound filters for improved and economicalfiltration. in high-viscosity fluids, cooling waterand plating solutions.

The Profile II filter cartridge is an absolute rated
depth filter. This all-polypropylene filter has acontinuously graded pore structure for built-in
prefiltration and long service life.

■ Tapered Pore Structure

Applications
These filters are the ideal choice for filtering
polishing slurries used for the following
applications; chemical mechanical planarization(CMP); hard disk drive (HDD) and bulk wafer
polishing. Profile II filters are recommended for
applications requiring the removal of particles
below 5 microns.

Continuously graded poreprefilter layer■ Nexis® A Series Filter
The Nexis A filter cartridge is a more economical
absolute rated depth filter. This all-polypropylene
filter features proprietary CoLD (Co-located LargeDiameter) fiber technology to enhance the filters’
strength and minimize contaminant unloading.
In addition, this filter has been optimized with agraded pore structure for outstanding dirt holding
capacity and long service life.

■ CoLD Melt TM Fiber Structure

Applications
These cartridges are suitable for filtering, slurries
and high viscosity liquids such as coatings
containing various suspended solids. Nexis ASeries filters offer highly cost effective
performance for applications requiring anabsolute rated filter to remove particles 5 micronsand larger.

The Claris filter cartridge is a nominally rated,
depth filter that utilizes an extruded core madefrom very dense fibers. It is Pall’s mosteconomical, depth filtration product.
Claris filters are available in a wide range ofnominal ratings from1 to 75 microns.

The Nexis T filter cartridge is a nominally rated
depth filter. This all-polypropylene filter features
proprietary CoLD (Co-located Large Diameter)
Melt fiber technology to enhance the filters’
strength and resist contaminant unloading. In
addition, this filter has been optimized with agraded pore structure for outstanding dirt holding
capacity and long service life. Nexis T filters areavailable in a wide range of nominal micron
ratings from 0.5 micron to 200 microns.

Applications
These filters are widely used for filtering large
volumes of liquid such as water in swimming
pools, non-critical process water and chemicals
in the photovoltaic industry.

Pleated-Depth Media
Pleated depth filters are formed using a pleated cylinder made of thick filter media with a tapered pore
structure. Three types of filters with different pleated cylinder structures are available.

■ Profile® Star Filter

Applications
Because of their pleated depth structure and very
high flow capabilities, Profile UP filters arerecommended for a wide range of fluids, withvarying viscosities and solids concentrations.

The Profile Star filter is an all-polypropylene,
pleated-depth filter that combines the exceptional
dirt-holding capacity of depth filters with the highflow rates of pleated filters. While the Profile Starfilter has a pressure drop and flow capability
comparable to many competitive, pleated, nondepth polypropylene filters, it excels in the removalof such contaminants as gels and agglomerates.

■ Poly-Fine® XLD Filter
The Poly-Fine XLD filter combines the best
attributes of depth and pleated filtration
technologies. This all–polypropylene productcombines the high flow capacity and low pressure
drop of pleated filters, with the gel retention
capability and long life of a depth filter. The multilayer media structure has been developed for finedispersion classification and gel retention.

Applications
These filters are the ideal choice for filtering both
high-concentration slurries and high-viscosity
pastes, where fine dispersion classification and gel
removal are required. A highly successful
application for Profile Star series, is filtering color
resists used in the manufacture of LCD color filters.

Applications
These filters are the ideal choice for the filtrationof high-viscosity and high-concentration slurries
where a more cost effective solution is required.

■ Profile® UP Filter
The Profile UP filter is an innovative combinationof depth and pleated filtration technologies. This
all-polypropylene product consists of a pleated,
depth medium using the Ultipleat® filter geometry
for high effective filtration area. The result is afilter having superior flow rates with very low
differential pressures.

Pleated Media
Pleated filters are formed using a pleated cylinder made of polypropylene filter media. Two types of products
made with different filter media are available.

■ HDC® Ⅱ Filter

Applications
These filters are the ideal choice for process waterand air where very high flow rates are required. HDC IIfilters are especially recommended for the removal ofliquid particles below 5 micron or airborne particles
below 0.1 micron.

The HDC II filter cartridge is a high filtration area,
all-polypropylene pleated cartridge exhibiting very
low differential pressures. Unlike otherpolypropylene pleated filters, the HDC cartridge
utilizes a proprietary medium construction
composed of a continuously varying fiber diameterto produce a pore size distribution from coarse(upstream) to fine (downstream). This uniqueconstruction permits more contaminants to be
trapped in the outer layers of the medium, thus
substantially increasing dirt-holding capacity.

■ Poly-Fine® Ⅱ Filter
The Poly-Fine II filter cartridge has a pleatedconstruction, providing for very low pressure drops
and high flow rates. This most economical pleated,
polypropylene product comes in a range ofremoval ratings from 0.45 to 200 microns.
Applications
These filters are the ideal choice for process waterand air when a more cost effective solution is required.
