Nexis® T Series Filter Cartridges

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.

Pall’s proprietary CoLD fiber media technology is designed
to assure efficient use of the entire gradient depth of the filter.
The CoLD MELT process produces a mixture of micro-thin fibers
intermingled and thermally bonded with large diameter CoLD
fibers to provide an integral support and fluid transport network.
The large internal void area created by the CoLD process
enables Nexis filter cartridges to capture more contaminant
than conventional cartridges while the rigid support fibers hold
the filtration fibers firmly in place. The result is less potential
random unloading of contaminant and more efficient filtration
under a variety of operating conditions.

Typical Flow vs. Differential Pressure for Application Sizing

Due to the very low flow resistance of the media in the more open grades, pressure drop is primarily related to turbulent loss through the center core. Flow rate is per 10" (25.4 cm) cartridge. For liquids other than water, multiply differential pressure by fluid viscosity (cP).
