BIO-Wheel® Emperor® Assemblies for models PF280B, PF280BD, PF400B, PF400BD, and PFE2.

BIO-Wheel® Assemblies - Various Models is rated 5.0 out of 5 by 1.
Rated 5 out of 5 by from Dropping Ammonia Levels I bought one as a replacement for my Emperor 400 and one as a spare as I purchased the 400 slightly used but not abused from a marine application. Unfortunately, replacing the bearings did not help as the axles (fiberglass) were too worn on one of the wheels. These Bio-Wheels are not the be all and end all for removing and/or neutralizing ammonia, but they do a pretty good job. However, I do not recommend replacing the wheels unless they are no longer functional.

Does this filter fit the Bio-wheel Emperor 400 Power Filter? I don't see a model#, but there is a 400 C on the bottom of the outside filter box.

Asked by: Marsa 34
The model number of your filter is molded into the cover that is on the top of the filter. If you have an Emperor, type Emperor 400 into our search bar and it will bring a link up for parts and for just the bio wheel. BREX
