Dr Thomas J. Schwalbe from TRM Filter examines how the dedusting of plants and processes in the pharmaceutical industry has particularly exacting requirements: maximum filtration performance protects against dust residue, and filter systems and their handling are usually subject to dust-tight containment. Systematic protection against process material leakage is achieved using tested and expert-approved, effective design solutions for explosion protection which enable reliable dedusting, even of highlypotent active ingredients (HPAPIs).
