Abstract
A ducted shelf for an open-fronted display unit employing air curtains. The shelf has a supply duct at a lower level communicating with a downwardly-facing forward discharge outlet and a return duct at an upper level communicating with an upwardly-facing forward return inlet. In front-to-back section through the shelf, a forward supply duct extension in front of the supply duct narrows forwardly above the discharge outlet and a forward return duct extension in front of the return duct reaches downwardly to the lower level of the shelf to lie forwardly of the supply duct. This beneficially reduces the thickness of the front of the shelf.
