Tablets are the dosage form which are most commonly used. The way to the finished product is long. Different sub-processes are necessary. Tablet presses and their de-dusting are part of these production processes. As of late a catridge filter type INFA-MICRON MPR works at Boehringer Ingelheim Hellas in Athens. The filter unit cares for a clean production of pharmaceutical products by gathering the dust at several suction points within the tablet press.
