Mark II Gas runs on gas heat and a small amount of electricity, so you can take it with you almost anywhere! This Donut Robot® fryer produces high quality, well formed cake donuts right out of the box, and makes excellent raised donuts with a few accessories. With the mini donut option, you can make both full size and mini donuts. The Mark II Gas is compatible with Donut Robot® Mark II Gas systems. While the fryer works, you can take care of other business! There’s no easier, more dependable way to make donuts.
