Recommended cleaning method of filters:
1.
Vacuum Clean – A few passes of a vacuum cleaner on the inlet side
of the filter will remove accumulated dust and dirt in seconds.
2. Blow with Compressed Air – point compressed air nozzle in
opposite direction of operating air flow (Blow from exhaust side
toward intake side)
3. Cold Water Rinse – Under normal conditions the foam media used
in the filters, require no oily adhesives. Collected dirt is washed away
quickly and easily using just a standard hose nozzle with plain water.
(Ensure filter is completely dry before reinstalling)
4. Immersion in Warm Soapy Water – Where stubborn air-borne dirt
is present, the filter may be dipped in a solution of warm water and
mild detergent. Then simply rinse in clear clean water, let stand until
completely dry and free of moisture, and return to service.
When replacing with a new filter, the filter must be provided by Rockwell
Automation or approved for use by Rockwell Automation. Replacement
of the filters is performed in the reverse order of its removal. Check that
there are no openings that would allow foreign matter to enter the drive.
