4.6.2 Cleaning the Filter
The shelf filter needs routine cleaning to ensure effective filtration and airflow. Since cleaned
air filters are less efficient and less permeable to air than new ones, Artesyn Embedded
Technologies - Embedded Computing recommends replacing filters with new ones after
three cleaning cycles.
Remove the filter before cleaning it.
There are four ways to clean the shelf filter:
 Vacuum clean: A few passes of a vacuum cleaner can remove accumulated dust and dirt.
 Oil-free compressor air: Point the compressed air nozzle in the opposite direction of the
filter's operating airflow (blow from the filter's exhaust side toward the intake side).
System Damage
Air Filter
Air contamination can pollute the air filter and obstruct the air intake of the system which
may cause system overheating and component damage.
To guarantee proper airflow through the system the air filter has to be replaced at least
every six months. Artesyn Embedded Technologies - Embedded Computing
recommends to replace the air filter every 90 days. Filter replacement frequency depends
on the environment the system is subjected to.
Air filters should be cleaned at least every 90 days or sooner, depending on the conditions
of the environment. Because central offices vary in physical location and cleanliness, check
your air filters every week after you first install your system. In a dusty environment, a filter
may need cleaning more often than a filter in a cleaner environment. Check the filters
frequently until you have a good idea of how often it needs cleaning. Based on your
findings, establish a regular cleaning schedule and keep a log to record the date of each
filter cleaning or replacement.
