Preheat Function

This model does not have a preheat function. Preheating ensures the air fryer reaches the optimal temperature before cooking, resulting in crispier and more evenly cooked food. Consider this if you want optimal results.

Digital Control Panel Function

The digital control panel allows for precise temperature and time settings, providing greater control over the cooking process. It simplifies selecting cooking programs and customizing settings. The touch control is easy to use.

Automatic Shut-Off Function

The automatic shut-off function turns off the air fryer when the cooking time is complete, preventing overcooking and ensuring safety. This offers safety and peace of mind, especially for busy individuals.

Dishwasher Safe Parts Function

The dishwasher-safe parts make cleaning the air fryer quick and easy, saving time and effort. This simplifies the cleanup process after cooking, making it easy to keep the air fryer clean and hygienic.
