Profile II Filter Elements

Summary

Product Identification

Profile® II filters are constructed entirely from chemically resistant polypropylene, designed with an absolute-rated downstream section and a continuously graded pore size upstream section to maximize service life. The manufacturing process uses no binder resins; fibers are intertwined to prevent media migration.

These filter elements are suitable for a wide range of corrosive and non-corrosive fluids, finding applications across diverse industries including chemical, petrochemical, photochemical, pharmaceutical, biological, electronic, magnetic tape, electroplating, food and beverage, cosmetic, veterinary, medical, and fermentation. They are utilized as both prefilters and final filters.

Available series include RF Series, RMF Series, and AB Series (Code 3 and Code 7 configurations).

Operating Limits

The recommended maximum pressure differential for Profile® II filters varies with temperature:

• 60 psi up to 30°C (86°F)
• 50 psi up to 50°C (122°F)
• 30 psi up to 70°C (158°F)
• 15 psi up to 82°C (180°F)

For applications where filters are heated above 50°C (122°F) and then cooled by 20°C (36°F) or more, AB Series elements are recommended.

Mechanical / Hydraulic

Dimensions:

• RF and RMF Series: 2½″ O.D., available in one-piece 10″, 20″, 30″, and 40″ length modules.
• AB Series: 2¾″ diameter, available in Code 3, 7, and 8 configurations.

Cartridge Characteristics (Table I): The datasheet provides detailed characteristics for various grades (003 to 1200), including:

• Liquid Service Removal Ratings at 99.9% and 100% efficiency (in µm).
• Gaseous Service DOP (0.3 µm) Efficiency %.
• Typical Clean Pressure Drop (Aqueous Pressure drop in PSI per GPM for a single 10″ cartridge).
• Typical Gaseous Flow (CFM of air per PSI per 10″ cartridge).
• Typical Liquid Service Flow (GPM/10″ Cartridge).

Notes on flow and pressure drop:

• Air flow data for grades 003-400 used 20 cfm/10″ module; grade 700 used 4 cfm.
• Pressure drop values are for a single 10″ module; for multiple elements, divide by the number of modules. For fluids other than water, multiply by viscosity in centipoise.
• For longer modules, flow rates increase proportionally. Flow rates do not account for internal diameter pressure losses, which become significant above 40 to 60 cfm.
• Values marked with (4) are extrapolated.
• Precise 100% removal efficiency evaluation for coarse grades (700, 900, 1200) was not possible with the test procedure utilized.

See the official PDF for exact tabulated values.

Materials of Construction (Ordering Options):

• Gasket Material: Alloy of Polypropylene and Ethylene Propylene Diene Monomer (EPDM) (Code H21).
• O-ring Options: Silicone (Code H4), Viton A (Code H), Ethylene-Propylene (Code J).

Housing Compatibility:

• RF and RMF Series: Compatible with Pall housing data sheets H2, H13, H14, H15, H16, H17, H18, H19, H36, H37, H38, H39. Can also be used with competitor housings accommodating 2½″ O.D. x 10″, 20″, 30″, and 40″ nominal length elements; however, sealing may be marginal for grades 030 (3 µm absolute) and finer.
• AB Series (Code 3, 7 and 8): Compatible with Pall housing data sheets H22, H26, H28, H29, H30, H31, H32, and H35.

Special Features

• Steam Sterilization/Hot Water Sanitizing: P grade AB Series elements are suitable for in-situ steam sterilization and hot water sanitizing.
