8-2 Servicing Process Air Filters
Important!
Operating the dryer without the process air filter installed voids
your warranty!
Filter cleaning is an important part of your dryer maintenance
program.
AD dryers have a single cartridge canister-type filter in the process
air loop. The filter protects blowers from plastic fines drawn in
from the drying hopper and prevents the desiccant from being
contaminated. Regular filter cleaning is essential to keep your
dryer operating at peak efficiency.
You can blow or vacuum the dirt out of the filter with compressed
air, but remember, it could become damaged from high-pressure
blowing.
