ActronAir Indoor Evaporator Fan Deck 15x11 S (SCA54, SCA62, SCA70) is the factory-specified fan deck for SCA54, SCA62, and SCA70 commercial package indoor units, providing the high-volume airflow required by these larger commercial coil configurations to maintain rated performance across the connected commercial duct network. On commercial systems operating in high-ambient environments, fan deck degradation typically presents as reduced airflow before mechanical failure -- early replacement prevents capacity loss at peak demand periods. Isolate power at mains before replacement -- live work on fan assemblies is dangerous and must only be performed by a qualified technician.
