Magnetic Impeller Assembly for the Emperor® 400.  White, also comes with black flow manifold cover.

I have two Emperor 400 filters I purchased about ten years ago. The impeller you're selling doesn't look like the ones I have. Was there a redesign? Will this work with my older model 400? Thanks.

Hi there, Mrkleen. You are right, the current impellers will not fit the older model Emperor. Unfortunately the old impellers are not available. You may be able to find them on auction sites but they will eventually need replacement.

No, we have changed the design of the impeller. The new item number is ML90777, and it comes with the flow manifold housing cover now. This will fit your older Emperor also. BREX
