Nexis® T Series Filter Cartridges

For Clarification and Particle Reduction

Nexis T filter cartridges are ideal for use in rigorous food and beverage clarification processes. Pall’s proprietary CoLD™ (Co-Located Large Diameter) fiber technology gives the Nexis T filters internal support combined with high dirt holding capacity. 

Continuous graded and fixed pores provide pre- and fine filtration within the same cartridge resulting in lower overall filtration and disposal cost.   

The Nexis T filter cartridges provide a typical nominal removal efficiency with consistent filtration performance. These cartridges are an ideal choice for food and beverage processes needing high-performance filtration at an economical price.

Operating Characteristics in Compatible Fluids

Maximum Differential Pressure	Recommended Change out Differential Pressure	Operating Temperature
4.14 bard (60 psid)	2.4 bard (35 psid)	30 °C (86 °F)
1.72 bard (25 psid)	-	66 °C (150 °F)
1.03 bard (15 psid)	-	82 °C (180 °F)

Compatible fluids are defined as those which do not swell, soften or attack any of the filter components

Sterilization and Sanitization

• Single open end (SOE) cartridges may be autoclaved for 30 minutes at 121 °C (250 °F) under no end load conditions. Cartridges should be cooled to system operating temperatures prior to use.
• Steam sterilization is not recommended.

Flow Rates

*For clean water at ambient temperature for liquids of viscosity other than 1cP multiply the ¢P by the viscosity in cP.

Quality

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