PROCOOL GRL-FLT40
Black 3 part 40mm Fan Filter.
Keeping the fans clean will extend the average lifespan. As well, keeping the air filtered will keep cabinets cleaner.
There will be a slight reduction in aiflow as the filter will restrict some airflow. A dirty filter can dramatically reduce airflow. It is important to keep the filters as well as the fans clean. Canned air is an easy means to keep things cleaned. Use often. :-)
Installation:
Attach the base to the intake side of the fan with the included screws.
Place the filter media in the cover and snap in place.
For rackmount fan systems, attach to the front of the panel for intake systems.
For exhaust systems, mount to the fan on the back of the panel.
