Airmax Pond Logic KoiAir 2 Diaphragm Kit

I was having a problem with my aerator and couldn't find the parts to fit. One pond place said I would have to just replace the whole thing because it didn't appear to be made anymore. I have a Pond Logic. This had the name in it but you never know since the models could be different. It looked the same and it was! My aerator works amazing now!
