Profile® A/S Series filters are constructed of an all polyphenylene sulfide (PPS) filter medium with 316 L stainless steel cores as standard. The elements have an absolute rated downstream section, and a continuously profiled pore size upstream section, which increases service life many-fold. Note the photomicrograph below. The elements are available in a broad range of absolute removal ratings.
The fibers in Profile A/S filters are continuous, for practical purposes. No binder resin or surfactants are used and the fibers are “bonded” by intertwining during the manufacturing process. The filter components meet the specifications for biological tests listed in the current revision of USP for Class VI plastics at 121 °C. Because of the inertness of the polyphenylene sulfide medium, Profile A/S elements can be used with many fluids up to 400° F (205 °C).
The Profile A/S filter has numerous applications in a broad range of industries that include chemical and petrochemical industries. Typical applications include:
- Amine
- Hot Water
- Glycol
- Sulfolane
- Condensate
- Methylene Chloride
- Naphtha
- Potassium Hydroxide
- Oxo Alcohols

- Continuously profiled pore size upstream section.
- Absolute rated constant pore downstream section. Note the continuously decreasing fiber diameter in the profiled upstream section and the constant fiber diameter in the downstream section.

The Profile A/S Series filter elements are aligned within Pall Profile II housings by installing the elements onto a tie-rod. The elements are then secured in place by a seal nut. When fully engaged, the tie-rod/seal nut assembly forms a knife edge sealing surface embedded into the filter medium at both the top and bottom of the element. The elements are secured in alternative housings by spring engaged sealing surfaces.

Depending on the fluid compatibility, Pall Profile A/S elements may be used at temperatures up to 400°F (205°C). Please contact Pall Corporation for guidance.
Disclaimer: The compatibility data represented in this chart is for general guidance only at the temperature noted. Because so many factors can affect the chemical resistance of a given product, you should pre-test under your own operating conditions observing applicable safety practices such as those given on the Material Safety Data Sheet for each chemical. If any doubt exists about specific applications, please contact Pall Corporation.
Operating Characteristics
- The recommended maximum differential pressure for the standard Profile A/S Series filters is 30 psid / 2 bard up to 400 °F/(205 °C) and 40 psid / 2.8 bard up to 200 °F/(93 °C)
Sizes
- Profile A/S Series filter elements are 21⁄2 in. O.D. and are available in one-piece 93⁄4 in., 10 in., 20 in., 30 in., and 40 in. length modules
Housings for Profile A/S Elements
- Pall offers a full line of filter housings. Please contact Pall for more information.
1The test procedure used for liquid service rating is an adaptation of ISO 16889 modified for fluid process applications to determine the particle size above which particles are quantitatively removed.
2Pressure drop in PSI per GPM water for a single 10 in. module. Multiply this value by the required flow to determine the total aqueous pressure drop. Next, for fluids other than water, multiply by viscosity in centipoise. If this calculated pressure drop is excessive, then divide this value by the number of 10" modules required to reduce this pressure drop to an acceptable level.
