to remove all dirt and suds (less than 40 psi, no nozzle). If the clean or downstream side of the filter has been contaminated with dirty water during the soak cycle, rinse from both sides.

•Dry the filter before re-using. Circulate warm air at less than 160ºF. Do not use a light bulb to dry the filter.

•Inspect for holes and tears by looking though the filter toward a bright light. Check for damaged gaskets or dented metal parts. Do not re-use a damaged filter.

6-3 Servicing the Process Air Filters (Models 850 through 2100)

On 850 through 2100 cfm dryers, the multiple high temperature [up to 350°F] process filters are located in the housing under the blower platform on the left rear corner of the dryer. These filters protect the centrifugal blowers from plastic fines being drawn in from the drying hopper. Regular filter cleaning will keep your dryer operating at peak efficiency.

Filter Cleaning/Replacement

•Turn off and/or lock out electrical power [and compressed air, if so equipped] to the dryer.

•Remove the hand knobs or threaded fasteners securing the filter access cover and remove the cover.

•Remove the nut on the center retaining rod to remove a filter cartridge.

•Blow or vacuum each filter until the filter is clean. If the filter is worn through or can't be cleaned, replace it.

•Remove the small fines cleanout cover from the lower back portion of the filter unit below the air outlet transition.

•Vacuum out the fines and reinstall the cover and gasket.

•Reinstall all the filter cartridges, tightening them securely.

•Replace the door or access cover, being careful to keep the gasket intact, if supplied.

Recommendations for Cleaning Heavily Soiled 850 through 2100 cfm Process Filters

Vacuuming

Try vacuum cleaning a soiled filter first. Vacuuming removes most large particles and surface contaminants, and may be all that’s needed the first time a filter is cleaned. Use a commercial duty [recommended] or household vacuum cleaner. Vacuum the filter from the air intake [dirty] side only.

Compressed Air Cleaning

Blow clean, dry compressed air up and down the pleats, blowing out the filter from the clean side. Don’t shoot the air in a criss-cross motion against the grain of the pleats - you won’t end up with a clean filter, and you might damage it.

Washing

As a last resort, wash the filter. This is only necessary when the pressure drop is too high due to fine dirt embedded in the filter or there’s been oily mist near the intake air location. Use a mild, low sudsing detergent and warm water. Soak the filter 5–10 minutes, then gently agitate for several minutes. Rinse thoroughly with clean water to remove all detergent. Let the filter dry completely before returning it to
