An enclosure with a sliding sash and extraction.
Also known as: Fume hood, Extraction cupboard
A fume cupboard is drawn as an enclosure with a sliding front sash and an extraction duct above, drawing air inward so vapours are carried away from the operator.
Encloses work and draws air inward so vapours are carried to extraction rather than into the room.
Contexts: Laboratory
Protects by air movement rather than by the barrier, so the sash height governs whether it works at all and a raised sash defeats it.
Contexts: Laboratory
A rectangular enclosure with a sliding panel across its front opening and a duct rising from its top, with arrows showing air drawn inward.
