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 filtration cycles 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.
CharacterizationThe tests are carried out according to the methods of the Technical/Analytical Work Group within the European Depth Filtration Association or in accordance with in-house test methods.

Important Note :
|T 120||Retention of activated carbon|
|T 500||Fine clarification (e.g. polyurethane, polymethacrylates, etc.)|
|T 1000||Filtration of viscous oils and highly visous oils|
|T 2600||Catalyst removal (e.g. from tensides and amines, from silicones, etc.)|

The depth filters conform to the Recommendation XXXVI/1 BgVV (German Federal Institute for Health Protection of Consumers and Veterinary Medicine) and meet the requirements of the Lebensmittel-und Bedarfsgegenständegesetz - LMBG - (Foodstuff and other Commodities Act), in particular §§ 5, 30 and 31; they can be used for cold filtration of foodstuff without any reservation.
