Recommendations for Cleaning and Replacing Filters

•Turn off and/or lock out electrical power to the dryer.

•Remove the threaded fastener securing the filter access cover, and then remove the cover.

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

Vacuuming

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.

Cleaning with Compressed Air

Blow clean, dry compressed air up and down the pleats, blowing out the filter from the clean side. Remove loose dirt from the filter with compressed air or a water hose. Compressed air

should be less than 100 psi (689.5 kPa/6.89 bars). Use a 1/8”

(3 mm) dia. nozzle at least 2” (5 cm) away from the filter. Don’t shoot the air in a crisscross motion against the grain of the pleats—you may damage it.

Washing

As a last resort, wash the filter. However, do so only if the pressure drop is too high from fine dirt embedded in the filter, or if oily mist is present near the intake air location. Soak in a solution of FM 1400 or comparable detergent and warm water from five to ten minutes, then gently agitate for several minutes.

Rinse thoroughly with clean water to remove all detergent.

Caution! Let the filter dry completely before returning it to service! A damp filter can contaminate the closed loop system of the dryer.

Do not use a light bulb to dry the filter. You should get satisfactory filtration after second or third washings; however, dirt-holding capacity of the filter decreases after each washing.

After each cleaning:

•Inspect the filter element. Briefly hold a light bulb behind the element and look for any fatigued paper or residual dirt. 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!

•Inspect the end plates. Any damage here can allow air to bypass the filter.

•Look for rust on the end plates and metal core. Rust particles can flake off and contaminate the dryer and resin.

•Check the gasket for damage. A damaged gasket allows contaminants into the process. Replace as needed.

•Allow the filter to dry before re-using. Circulate warm air at less than 160ºF (71ºC). Do not use a light bulb to dry the filter.
