How big/wide are they and what shape ?kirkh said:One pump is a Danner, one is a Eheim, used to use Rena, could get part's for Rena's back in the day. They are felt filters, there's just many different grades of felt, wondered if anyone knew more than I do. It's 1/4" thick felt.
You're quite welcome ... :thumb:kirkh said:I may have found the proper bulk material, felt in an F10 grade looks right. I'm going to contact the companies that supply bulk material and ask for a grade recommendation.
1/4 inch thick, about 3/4 inch round, I'll just cut to size. Should also work on my air compressor in the garage.
