A fan oven is a popular type of oven that uses a fan to circulate hot air around the food. This helps to distribute heat evenly and cook food quickly. Some synonyms for fan oven include convection oven, turbo oven, circulating oven, and air fryer. Convection ovens are similar to fan ovens but also have heating elements that generate heat. Turbo ovens are often smaller and more portable than fan ovens. Circulating ovens also use a fan, but are typically used in commercial or industrial settings. Air fryers are similar to convection ovens, but focus on healthier cooking by using little to no oil.
