Middle Atlantic KO-AWFP2 – Assembled Rear Door Fan Kit, 5.25" LKO

Product Overview

The Middle Atlantic KO-AWFP2 is a factory-assembled rear door fan kit designed for the 5.25" laser knockout (LKO) openings on Middle Atlantic WRK, MRK, and ERK Series enclosures. The kit converts a standard solid rear door into an active thermal management surface without rack disassembly or custom fabrication. It ships with a mounting panel and two 120V fans, ready to install once the laser knockout is removed. For integrators standardizing on configurable rear doors, this is the direct-fit cooling option for the 5.25" knockout pattern.

Product Description

Heat is the most common cause of premature equipment failure in commercial AV and IT installations, and rear door airflow is one of the most effective places to address it. Middle Atlantic builds its WRK, MRK, and ERK Series solid rear doors with laser knockouts so the same door can support passive venting, filtered intake, or active fan cooling depending on the heat load of the installed equipment. The KO-AWFP2 targets the 5.25" LKO size and arrives pre-assembled, which shortens equipment rack installation time on site. Punch out the knockout, mount the panel, and connect the 120V input to complete the upgrade. Because the kit includes two fans on a single panel, it moves more air through the door than a single-fan solution while occupying one knockout location. This makes it a practical retrofit for racks that have taken on additional amplifiers, network switches, or media servers since the original commercial AV deployment. The kit pairs with KO Series vent and filter kits when a balanced intake and exhaust path is required across the door. For projects outside North America, Middle Atlantic offers the IKO-AWFP2 international version for 220-240VAC service.
