Questions and Answers
The round air filter mounted on the bottom of all Rena Air model pumps should be replaced when dirty to avoid damage to the air pump valves and increased clogging of diffusers. The 301 series pumps use either large version (pictured above) filters or the standard size filters ( 702C1 ) found on the Rena Air series pumps.
Dit seems like this filter is smaller than the filters for rna air pump 100-400 series. Will this fit rena air pump 50? What is the exact diameter of this filter?
We sell only one filter size. The filters for the 301 are the same size filter as used on the discontinued Rena Air series pumps 100-400. Originally the 301 filters were much larger and had a plastic cover over the filter. We still have some of these if your pump is very old. It is much larger. You can call our offices if you need to purchase that.
The Rena Air 50 has a separate filter which is not on this site since that pump has been discontinued. You might try Frog Pond Aquatics on Ebay. They often sell hard to find items like that.
