Ultipor® GF Plus Filters – AB Cartridge Style

For Particle Removal

Ultipor GF Plus filter cartridges are made with positive Zeta modified glass fiber media for enhanced filtration efficiency for fluids in the food and beverage industry.

In addition to a high particulate removal efficiency and low pressure drop, the positive charge enables the Ultipor GF Plus filter to effectively remove submicron haze particles from a wide variety of aqueous and slightly alcoholic food and beverage products. The single open ended (SOE) configuration is designed to fit into sanitary housings.

Ultipor GF Plus filter cartridges are suitable for exposure to repeated hot water and in situ steam sanitization cycles for longer service life.

Operating Characteristics in Compatible Fluids1¹

Maximum Differential Pressure	Operating Temperature
5.5 bard (80 psid) (forward pressure)	50 °C (122 °F)
4.1 bard (60 psid) (forward pressure)	80 °C (176 °F)
300 mbard (4.4 psid) (reverse pressure)	In normal operation or in-situ steam sterilization

Sterilization and Sanitization

Media	Temperature	Cumulative Time/30 minute Cycles2
Steam	125 °C (257 °F)	25 hours / 50 cycles
Hot Water	85 °C (185 °F)	25 hours / 50 cycles

¹1 Compatible fluids are defined as those which do not swell, soften or attack any of the filter components.
²Measured under laboratory test conditions. The actual cumulative time depends on the process conditions. For applications requiring Sterilization or Sanitization Pall recommends the use of Code 7 adaptors to ensure filter sealing after cooling. Cartridges should be cooled to system operating temperature prior to use. Contact Pall for recommended procedures.

Quality

• Cartridges produced in a controlled environment
• Manufactured according to ISO 9001:2008 certified Quality Management System

Media	Particulate Rating (ß-5000)	Pressure Drop vs Liquid Flow Rate3 per 10" element
GFHZ	≤ 1 micron	10-15 mbar at 10 L/min (0.15 - 0.22 psi at 2.6 US gallons/min)
GFNZ	≤ 2 micron	~7 mbar at 10 L/min (~0.1 psi at 2.6 US gallons /min)

³Typical initial clean media differential pressure (dP) per 250 mm (10") cartridge for water at 20 °C (68 °F); viscosity 1 centipoise. For 508, 762 mm and 1016 mm configurations divide the differential pressure by 2, 3, and 4 respectively.
