With a deep fryer, you have to cook outdoors. Even with an electric rig, there's s lot of steam and vaporized oil and 99.9% of the kitchen fans in the world won't handle that.
If you're going to cook outdoors, get a propane gas rig. You can share the gas from your gas grill. The gas model will be MUCH, MUCH faster.
