Practical guide to semiconductor cleanroom design — ISO 14644-1 class selection, airflow strategy, vibration control, and 6-step implementation procedure for advanced fabs.
2026 fume hood selection guide: ducted vs ductless, CAV vs VAV, face velocity 0.4/0.5/0.6 m/s, PP/FRP/stainless/PVDF materials, perchloric-acid rule, ANSI Z9.5 and EN 14175-3 references, 4-step selection workflow.
Chemical laboratories need ISO 7-8 modular cleanrooms with explosion-proof (ATEX/IECEx) equipment, three-zone pressure cascade, and chemical-resistant materials. This 2026 guide covers ISO class selection, Ex zone classification, PP/FRP/SS 316L material choice, and full DQ/IQ/OQ/PQ validation.
