The T series depth filter sheets from Pall includes 10 different retention rates.
Grades T 120 to T 950 are used for clarifying filtration. Due to their positive ZETA potential, these depth filters possess a high adsorption capacity.

In contrast, grades T 1000 to T 5500 are designed for coarse filtration. They are characterized by a more open structure and combine very high outputs with long in-service life due to their high dirt-holding capacity.

Grades T 1000 to T 5500 have proved successful in the filtration of viscous media, for the retention of gel particles and coarse dispersed substances at low differential pressures. Furthermore, they can be inserted into plate and frame kieselguhr filters to retain the pre-coat filter material.
