I’m curious about the data associated with a air filter I just purchased. I am changing over to a paper filter from a oiled mesh type, aka ‘space ship’, using the same canister or housing. Will be using a Carter four barrel. I would think the Carter would be rated around 400 or so CFM’s. The filter data states 25 CFM. This filer is about 4”x8”and round. What if anything does the filter data mean. Heck, my big lawn mower uses more than 25 CFM. THANKS.
