I believe that he has an EL II system. That one has 2 smaller compressors
that as far as I know, there is not a rebuild kit available. These
compressors slooowww dowwwnnn after time because their permanent alnico
magnets lose their field strength. There may be a fix for those motors, but
I personally don't know of one. Because those compressor heads also contain
some of the solenoids that the EL II system uses, simple replacement of
them with VIAIR or similar compressors won't work. There are some junkyard
replacements that will work, but they are scarce. So, that leaves few
options. Check with Jim K and other vendors. They may have a fix that will
work.
