Is there a bar that has 6 holes in it spraying the biowheel that you need to pull out now and then to unplug with a brush? If it has one, then it's an emperor. Penguins don't have these. But both the Penguin and the Emperor have the feature of turning flow up and down. And for the spraybar, you can turn it also, to adjust the angle of spray that you prefer.

Either way, they are both excellent filters IMO
Enclosed is 3 pics of the Emperor spraybar.
Eeekkkkk, I should have taken pics of my other Emperor 400. Biowheels are much cleaner, lol. It's new of course, still cycling and building up colonies.
