Nuclear Fume Cupboard

A fume cupboard is a specialist containment unit designed to protect operators and the surrounding environment during potentially hazardous processing tasks involving powders, vapors, solvents, or toxic substances. It works by drawing air from the room through a partially open sash window, creating a controlled airflow that prevents harmful materials from escaping the work area. This air is then filtered—typically using HEPA or carbon filters—and either recirculated or safely exhausted.

Fume cupboards are essential across critical industries including pharmaceuticals, chemicals, defense, nuclear, and advanced materials. Hosokawa’s tailored solutions combine high-integrity airflow control with operator safety, compliance, and ease of operation—making them ideal for environments demanding stringent containment.

How it Works

Hosokawa Micron’s Nuclear Fume Cupboards operate by drawing contaminated air into the enclosure through the front sash, creating a controlled airflow zone. The air moves uniformly across the workspace, capturing airborne dust, vapours, or particles and routing them through HEPA or carbon filters.

Depending on the design, air is either safely discharged outside or recirculated after purification. Integrated sensors maintain airflow velocity at safe thresholds (>0.5 m/sec) and alert operators if performance drops. With safety features such as sash alarms, explosion protection, and filter change indicators, our fume cupboards ensure consistent compliance and peace of mind.
