- Air filter
The SRFILTER comes prefabricated and ready to install in standard 48U rack enclosures on the inside of the door. Vertical Velcro strips will need to be trimmed accordingly to accomodate 45U, 42U and 25U enclosures. When a filter becomes dirty or worn from use, be sure to replace. Velcro pieces can remain attached to the door, with no need for replacement.
