How does deep-frying without oil work?

Air frying involves cooking food with hot air. This circulates around the food, creating a crispy texture. Air frying is deep frying without oil.

The iCombi Pro, and the iHexagon, work together with the CombiFry like a high-performance hot-air fryer for the hospitality industry – but it can also steam, grill, bake, roast and much more. So you only need one cooking system for many cooking applications.
