Convection oven

Convection ovens or fan ovens or turbo ovens augment a traditional oven by circulating heated air using a fan. The actual fan motor is in a separate enclosure to keep from overheating. Food warms faster in a convection oven since the moving air strips away the thin layer of air which otherwise would surround and insulate the food. Technically, all ovens have natural convection currents, a lot depending on food placement and position of the heating elements. For this reason a more accurate term would be "forced-convection oven." The popular term, "convection oven" could therefore be construed as a shortened version of this more precise name.
