Profile® II RFN Depth Filter Series – Gas, Liquid Filter Cartridges
For Liquid and Gas Applications
Profile II RFN Series depth filter cartridges are for liquid and gas applications such as chemical, petrochemical, paint, resin coating, and food and beverage. They are comprised of an all-nylon filter medium with glass-filled polypropylene cores and available with glass-filled nylon cores for use with xylene, toluene, or other aromatics and high temperatures. There is no binder resin as the fibers are “bonded” by intertwining during the manufacturing process. As a result, these depth filter cartridges show no media migration.
Why Choose Profile II RFN Series depth filter cartridges?
The Profile II RFN elements have an absolute rated downstream section leading to 99.98% efficiency in liquid and a continuously profiled pore size upstream section for increased service life.
- All nylon filter medium with glass-filled polypropylene cores
- Increased service life
The Profile II RFN filter has numerous applications in a broad range of industries such as chemical, petrochemical, pharmaceutical, paint, resin coating, food, beverage and cosmetics.
Chemicals and Polymer:
- Chemicals - Final product (liquid), raw material (gas, air, liquid) and intermediate product (other)
- Petrochemicals (Amine, Benfield, other solvent loops)
- Polymer - Carbon fiber, nylon and polyurethane production
Oil and Gas:
- Upstream Injection Water & SRU
- Midstream LNG acid gas
- Midstream glycol filtration
- Midstream Process Water
- Refinery Amine Systems
The recommended maximum pressure differential for the standard RFN Series filters is 75 psi up to 86 °F (30 °C), 50 psi up to 158 °F (70 °C), and 35 psi up to 180 °F (82 °C). For the GN Series filters with glass filled nylon cores, recommended maximum pressure differential is 90 psi up to 86 °F (30 °C), 80 psi up to 158 °F (70 °C), 70 psi up to 212 °F (100 °C), and 50 psi up to 300 °F (150 °C).
If the fluid filtered is compatible with polypropylene and temperature below 194 °F (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.

2 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.
3 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.
