    摘要: A clean dry air generating unit that includes a fan filter unit and a dry air generating apparatus arranged within a chamber of closed construction. The fan filter unit includes an open air introducing fan, a chemical filter, and a HEPA filter. The chamber of closed construction is supplied air through the fan filter unit which is then supplied to the dry air generating apparatus. Clean dry air is fed from the generating unit to an area outside of the chamber or can be reintroduced to the generating unit. The apparatus can continuously supply clean dry air at a lower cost.
