On this page, you can find our entire assortment of hot air ovens. The difference between an hot air oven and a conventional oven can be found in the dispersion of hot air inside the oven. Hot air ovens evenly disperse the hot air throughout the oven with help of a fan. This way, meals are heated up quickly and evenly. In a conventional oven, the hot air rises up from below. That's why it's important to place your food in the middle of the oven, to ensure that everything heats up evenly. Preheating a conventional oven takes longer, but the temperature remains consistent throughout the baking process. This makes conventional ovens more suitable for baking.
