Ductless Fume Cupboard Guides (Recirculating Systems & BS EN 17242)
Ductless fume cupboards, also known as recirculating systems, offer a flexible alternative to traditional ducted installations. However, selecting and using these systems correctly requires a clear understanding of their capabilities, limitations, and applicable standards.
These systems rely on effective filtration and correct application to ensure safe operation, making it essential to understand both their performance characteristics and the limits of where they can be used.
This section provides practical guidance on ductless fume cupboards, including BS EN 17242 requirements, filtration considerations, and key factors that affect safety and performance. It is designed to help laboratories determine when ductless systems are appropriate and how to ensure they are used safely and effectively.
For a broader comparison, our guide to ducted vs ductless fume cupboards explains how these systems differ and how to select the right solution for your application.
