ActronAir Fan Wheel Guard (Top) suits LRE-100AS is the top fan wheel guard for the LRE-100AS Ultra Slim ducted indoor unit, providing the upper half of the protective shroud that channels airflow through the indoor fan wheel while preventing contact with the rotating assembly. The LRE-100AS fan wheel guard is a two-piece assembly -- this is the top half only, order LRE10003B for the bottom half if both pieces require replacement. Ensure power is isolated before removing or replacing any fan guard components.
