Profile® II RFN Series Filter Elements

Profile® II RFN Series filters* are composed of an all nylon filter medium with glass filled polypropylene cores as standard. They are also available with glass filled nylon cores. The elements have an absolute rated downstream section, and a continuously profiled pore size upstream section, which increases service life many-fold.

The fibers in Profile II RFN filters are for practical purposes continuous. No binder resin is used —the fibers are “bonded” by intertwining during the manufacturing process. As a result , Profile II RFN filters show no media migration.

Fluid Capability

The materials of construction of the standard RFN Series filters permit application in a very wide range of liquids, and gases. For use with hot vegetable and mineral oils, which cause the polypropylene core to swell, the GN Series, with a glass filled nylon core, is preferred. For use with xylene, toluene or other aromatics, and for high temperatures, the glass filled nylon core is required. The Profile II RFN Series nylon filters should not be used in any oxidizing conditions or with water above 115°F (40°C).

Operating Characteristics

The recommended maximum pressure differential for the standard RFN Series filters is 75 psi up to 30°C (86°F), 50 psi up to 70°C (158°F), and 35 psi up to 82°C (180°F). For the GN Series filters with glass filled nylon cores, recommended maximum pressure differential is 90 psi up to 30°C (86°F), 80 psi up to 70°C (158°F), 70 psi up to 100°C (212°F), and 50 psi up to 150°C (300°F).

If the fluid filtered is compatible with polypropylene and if the temperature is below 90°C, Profile II RF Polypropylene Series elements, described in Data Sheet E1 and Bulletin PRO 400, may be suitable. Pall Corporation’s Scientific and Laboratory Services group will supply compatibility information for both nylon and polypropylene upon request.

Sizes

The Profile II RFN Series filter elements are 21/2" O.D. and are available in one piece 10", 20", 30", and 40" length modules.

Housings

Housings are available in polypropylene, other polymers, carbon steel and stainless steel. Refer to brochure SUM 200 for further details.

¹ Extrapolated values.

² Air flow used for these data was 20 cfm/10” module, except grade 700, which was run at 4 cfm.

³ Pressure drop in PSI per GPM for a single 10” module. For multiple elements, divide by number of modules. For fluids other than water, multiply by viscosity in centipoise.

⁴ For longer modules, increase the flow rates listed in proportion. The flow rates listed do not take into account pressure losses due to flow in the internal diameter of the element, which becomes significant above about 40 to 60 cfm.
