There’s literally no difference between a conventional oven with a fan forced function and an air frier.
My regular, full-sized convection oven has an air fryer mode. The main difference with the normal convection mode is that the fan runs much, much faster in air fryer mode. Because hot air circulates faster over the food, heat is transferred at a greater rate.
