Safe dedusting and grinding of active ingredients
The market for containment solutions is growing. The current GMP and REACH regulations are also fuelling this trend. At POWTECH 2023, numerous suppliers presented interesting solutions for handling toxic powders up to OEB 6. In this article, we present current solutions for dedusting, grinding and cleaning under containment conditions.
In pharmaceutical and chemical production, highly active substances increasingly need to be handled safely or protected from contamination. In addition to the safe sampling, dosing and processing of hazardous substances, for which we described solutions in Part 1 of our series of articles on containment, the safe separation of dusts and the safe grinding of highly active substances are also important.
Highly developed solutions for dedusting and grinding under containment conditions
HET-Filter recently presented new HEPA filter systems that can be customised to meet stringent explosion protection and containment requirements thanks to their modular design. These systems filter fine dusts and suspended particles with an efficiency of over 99.995 %, achieving clean gas values of up to 0.0001 mg/m³. They fulfil the safety requirements up to containment level OEB 5 and are suitable for both low and high volume flows.
The internal HEPA filter cell of the HETdynamic filter system regenerates automatically if the dust load is too high.
