Kinetix MMA Asynchronous Main Motors Installation Instructions
Replace, Inspect, and Maintain Blower Filters
Filter media is made of synthetic fiber and has a corrugated matte to help increase the effectiveness. It must be properly cleaned and maintained to be effective.
Axial Blower Filter
There is no axial filter available. The customer is responsible for any filtering and impacts of airflow that would occur because of an installed blower filter.
Radial Blower Filter
On motors equipped with a filter, periodically inspect, clean, or replace the filter. If a filter is installed, avoid operating a motor without a filter in place. The air filter must
always be kept in good working condition. Dirty air filters affect the performance of the motor and may cause overheating and the intervention of the thermal switches.
A clogged air filter is directly related to the degree of impurity of the intake air, and so it is not possible to say what the average time between inspections and cleanings is.
Normally, conduct cleaning about every 200 working hours, however, there are cases when the work is required more frequently.
Radial blower filters must be inspected, cleaned, and replaced regularly. Air
filters are not provided as a replacement part from Rockwell Automation. Use
the information in
to source a filter. To replace a radial blower filter,
follow these instructions:
1.
Remove power from the motor and de-energize the system.
2.
Loosen the screws that secure the filter to the blower air inlet.
3.
Slide the filter out.
4.
Clean or replace the filter. See
• Blow out filter.
When blowing out the filter, apply compressed air from the
internal surface of the filter outward, being careful not to blow the
dirt inside the motor. See
• Replace filter. See
for filter dimensions.
5.
Reinstall filter.
6.
Insert and hand-tighten the screws that secure the filter.
