Convection Oven +

A convection oven (either a fan-assisted oven or a fan oven) is an oven that has fans to circulate air around food. Conventional ovens, which do not have fans, rely primarily on radiation from the oven walls, and to a lesser extent, on natural convection caused by temperature differences within the oven, to transfer heat to food. In contrast, the fans in convection ovens allow more heat to be transferred via convective heat transfer. Fans help distribute heat evenly around the food, removing the blanket of cool air that surrounds food in an oven, allowing food to cook more evenly in less time and at a lower temperature than in a conventional oven. A fan oven has a fan with a heating element around, that provides the heat. A fan-assisted oven that use a small fan to circulate the air in the cooking chamber, a conventional oven with a circulating fan.
