This section describes maintenance procedures which will increase the longevity and 
efficiency of your dehumidifying dryer.  Perform them at the regular intervals listed on the 
dryer checklist on the previous page. 

Dehumidifying 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. 

•  Turn off and/or lock out electrical power to the dryer. 
•  Remove the threaded fastener securing the filter access cover, then remove the cover. 
•  Remove the nut on the center retaining rod to remove the filter cartridge. 

 

                 

 

 
 
 
 
 

Try vacuum-cleaning a soiled filter first. Vacuuming removes most large particles and 
surface contaminants, and may suffice for the first time you clean a filter. Use a commercial-
duty (recommended) or household vacuum cleaner. Vacuum the filter from the air intake 
(dirty) side only.
