Chapter 3 Component Definition and Maintenance
If the drive is running, the filter must be replaced as soon as possible so foreign
material is not drawn into the drive.
Care must be taken in removing the filter, to prevent dirt that has accumulated on
the inlet side of the filter from being sucked into the drive. It may be difficult to
remove the filter material without tearing it due to the suction at the air inlet.
Recommended cleaning method of filters:
• Vacuum Clean – A few passes of a vacuum cleaner on the inlet side of the
filter will remove accumulated dust and dirt in seconds.
• Blow with Compressed Air – point compressed air nozzle in opposite
direction of operating air flow. Blow from exhaust side toward intake side.
• 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)
.
• 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.
