6-2 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.

Our dehumidifying dryers have a single cartridge canister-type filter in the process and conveying air loop. The process filter is mounted above the process blower on the rear of the dryer. The conveying filters are located under the drying hopper next to the conveying blowers. These filters protect the blowers from plastic fines drawn in from the drying hopper. Regular filter cleaning is essential to keep your dryer operating at peak efficiency.

You can wash or blow out the filters, but remember, you reduce dirt holding capacity with each washing. The risk of dirt reaching the clean side of the filter during cleaning, plus possible filter damage from high pressure washing or blowing, makes washing a gamble.

You can carefully clean or wash the filter when airflow becomes restricted. Do not wash filters more than six (6) times or use them for more than a year, whichever comes first.

Use a detergent that won’t damage filter media. Such a detergent permits easy removal of dirt particles through flushing and rinsing. An effective detergent removes the fine particles from the pores of the filter media.

The filter manufacturer recommends FM 1400 washing compound. It is formulated specifically for air filter element cleaning. It is non-sudsing and works in hot or cold water. FM 1400 contains biodegradable synthetic detergents and is non-phosphate, non-NTA. For more information, contact Filter Service Corporation, 2603 A West Main, Farmington, NM, 1-505-326-1127.
