Tunze Power Magnet Identification

[thrlride]

Hello,

I found a tunze power magnet in my collection of fish tank supplies and have no idea which model it is. I don't see any part numbers listed on it to identify which model magnet it is.

Is there a way I can identify which one I have?

The color of the felt pad is the easiest way, 0220.530 will have a green felt pad, a 0220.540 will have blue, 0220.550 or 0220.560 will have white. If the inside and outside have the same weight it is 0220.560.

Thanks Roger, it looks like I have the 220.540 model as my felt is blue. It seems so much more powerful than the magfloat I've been using.
