An 8L dual air fryer is a kitchen appliance with two separate cooking baskets that combine for a total 8-liter capacity, allowing you to cook two different foods at once. It uses a rapid, 360° hot air circulation system to cook food faster and with less fat than a conventional oven. Key features include independent controls for each basket, a sync/match function to have both dishes finish at the same time, and a digital interface with preset programs, timer, and temperature controls.
