ActronAir Indoor Evaporator Fan Deck 10x10 S 2HP ECM is the highest-output fan deck in the ActronAir residential range, providing 2HP ECM variable-speed performance for large-capacity ESP Plus and Ultima indoor units where maximum airflow volume and static pressure capability are required to serve extensive multi-zone duct systems. At 2HP this assembly draws the highest current of any single indoor fan deck -- the circuit supply, isolator, and indoor PCB current rating must all be confirmed against manufacturer specifications before replacement. Isolate power at mains before replacement -- live work on fan assemblies is dangerous and must only be performed by a qualified technician.
