An 8L dual air fryer is a kitchen appliance with a total capacity of 8 liters, divided into two independent cooking baskets, allowing two different foods to be cooked simultaneously. It uses rapid hot air circulation technology, features a digital control panel with preset programs, and allows for independent temperature and timer control for each basket. The dual design, often with a "Sync" or "Match" function, enables different foods to be ready at the same time, making it convenient for cooking full meals for families.
