Wash-Down Fume Cupboards FAQ

What is a wash down fume cupboard?

A wash-down fume cupboard, also known as a perchloric hood, is a ducted extraction system for containing chemicals like perchloric vapors, residues, and particulates. It prevents perchloric salt formation with internal water filtration. This specialized unit ensures laboratory safety by effectively managing hazardous substances.

A wash-down fume cupboard incorporates water sprinklers behind the rear baffle plate, preventing perchloric acid crystallization. Its top-down filtration halts residue buildup and explosive risks. Connected to a drainage system, excess water is removed, while air extraction occurs through a roof-mounted ventilation stack.

The primary difference lies in their mechanisms of dealing with hazardous substances. Wet-scrubber fume cupboards utilize a wet scrubbing process to neutralize toxic vapors before release, while wash-down fume cupboards prevent perchloric acid crystallization by rinsing surfaces with water jets, particularly behind the rear baffle plate.

The time required for installing a wash-down fume cupboard can vary based on factors like the complexity of the setup, site preparation, and specific customization needs. Generally, installation may take anywhere up to 7 days, depending on the circumstances and requirements of the installation site.
