Check Air Dryer
Air Dryers
Air Dryers have internal maintenance systems that clean
out the accumulated moisture frequently and can therefore
work with long maintenance intervals. Eventually the
drying medium fills up and needs replacement. Change
the cartridge when the medium is filling up more than
usual. This service rate varies upon the application.
Dryer manufacturers recommended changing cartridge
every two to three years but intervals vary per application.
The only dryer with regular maintenance is the Midland,
which requires changing of the coalescent filters every
year.
