Middle Atlantic FILTER-R-4-2K Reusable Rack Filter

Product Description

The MIDDLE ATLANTIC - U.S. - LEGRAND FILTER-R-4-2K is a reusable air filter designed for rack enclosure installations. Sold as a pair, it fits 4-opening rack configurations and provides particulate filtration to protect sensitive equipment housed in rackmount cabinets. This type of filter is typically installed by AV integrators, IT technicians, and low-voltage contractors working on equipment racks in commercial or residential settings. The reusable construction allows for cleaning and reinstallation rather than single-use replacement, reducing ongoing maintenance costs over the life of the rack.

This filter pair is suited for use in ventilated rack enclosures where airflow management and dust control are priorities. Typical applications include server rooms, AV equipment closets, data centers, and any environment where rack-mounted electronics require protection from airborne particulates. The 4-opening configuration makes it compatible with standard rack filter panels designed around that opening count. Installation is straightforward and requires no special tools in most rack configurations.

Installation Notes

Installation is performed by low-voltage technicians or AV integrators as part of rack enclosure setup or maintenance. Power down or de-energize sensitive rack-mounted equipment before servicing filters to prevent ESD damage or airflow disruption during the swap. Filters should be cleaned per manufacturer guidance and allowed to dry fully before reinstallation. Follow applicable low-voltage installation codes and best practices for the installation environment.
